01The idea
Bitcoin, from the island
The identity joins three things: the global currency, the Sinhala language, and a guardian from Sri Lankan mask craft. Every part of the logo carries one of them.
Set in lowercase, bold and slanted forward. It names the product plainly, in the world's language for it.
Deepa, “island”. Custom Sinhala lettering in Bitcoin orange. It puts Sri Lanka inside the name.
The slogan. Sri Lanka has long been called the Pearl of the Indian Ocean; here the pearl belongs to Bitcoin's creator.
The Yaka mask is the brand's symbol. It is drawn as fine line art in a flame gradient, from amber at the base to red at the tips. It gives Bitcoin Deepa a face that no other Bitcoin company has, and wherever the brand needs a mark without words, the Yaka is that mark.
02Logo
The primary logo
The stacked lockup, mask above wordmark, comes in two versions. Pick by the ground: black wordmark on light, white wordmark on dark. Use it everywhere it fits at 120px wide or more.
The Yaka is the symbol
The mask stands for the brand on its own: social avatars, merchandise, watermarks, large crops on posters and packaging. Use the gradient version on white or black, and the single-colour versions for one-colour print, engraving and embossing.


Two more ways the brand uses the mask: cropped off the edge of a layout, half in frame, and as a faint watermark behind content.


Bold Yaka
The same mask with every line drawn heavier, so the detail in the crown and the hood rays holds up when the symbol is small or reproduced roughly.
- Use it below about 200px on screen, and for embroidery, engraving, stamps, signage seen from a distance and small print.
- Use the original line weight everywhere else; it is the primary symbol.
- Same colours and gradient as the original; never mix the two weights in one layout.
Half Yaka
The mask cut down its centre line and set full height, so it fills a tall panel and bleeds off one edge: covers, banners, pull-ups and slide backgrounds. Use the gradient version on white or black; the cut side always sits flush on the panel edge.
- Left-aligned: the right half of the mask, sitting on the left edge of a layout.
- Right-aligned: the left half of the mask, sitting on the right edge, as on the LinkedIn covers.
- Keep the cut exactly on the layout edge; never show the straight cut line inside the frame.


Laser-eyed Yaka
The Yaka with the brand's red laser flare on both eyes, used exactly as drawn: a white-hot core, long thin cross rays and a soft red halo. The flare sits low in each eye, in the lower part of the inner oval, not at its centre. It nods to the “laser eyes” of Bitcoin culture and gives the mask a living presence on dark layouts such as covers, banners and event screens.
- Dark grounds only (Genesis Black or Cold Storage Charcoal). On white the red glow loses its light.
- Use the artwork as supplied; keep the lasers red or light only one eye on a full mask. Edge crops that show a single eye are fine.
- One laser-eyed Yaka per layout. It is a hero moment, not a pattern.


Heroes, posters, packaging and campaign openers, where there is room to read Pearl of Satoshi.

App icon and orange version
The දීප symbol is the app icon; see the App icon section. The orange-ground files are covered under Backgrounds.


Navigation bars, email footers, and anywhere the stacked logo would be under 120px wide.

“Powered by” lockup
For products and campaigns that Bitcoin Deepa backs, such as the Lightning card and the book launch: “Powered By” in Nunito Sans, small and right-aligned above the horizontal wordmark. Keep the sponsored product's name as the hero and the lockup at the foot.
03App icon
The app icon
The app icon is the දීප symbol: the orange Sinhala glyph on a white tile. It is the one place the brand appears without the Yaka, because at icon sizes the mask's fine lines fill in.
Light and dark appearance
Light
Orange glyph on a white tile. The default icon, and the one for light-mode home screens and light browser tabs.
Dark
The same orange glyph on a Cold Storage Charcoal (#1D1E1D) tile, for dark-mode home screens (iOS 18 and later supports a separate dark icon) and dark browser tabs.
Sizes






Masks and safe zone



The dashed circle is Android's adaptive-icon safe zone (the inner 66% of the tile). The standard glyph sits inside it, so no mask crops it. Supply a square 1024px master with no transparency; the phone or store rounds the corners.
Orange glyph, plain tile
#F8931A, on #FFFFFF (light) or Cold Storage Charcoal #1D1E1D (dark). No orange tile, no gradient.Nothing else on it
Why not the Yaka

04Backgrounds
Three approved grounds
White, black and Bitcoin orange. On orange the logo changes: the mask turns single-colour and දීප turns black, because orange on orange disappears. Use only the two orange-ground files there.



Photos: place the logo only over a calm area where the matching version stands out clearly. If the area is busy, put the logo on a solid white or black panel first.
05Clear space & size
Give it room
Keep clear space on every side equal to the height of the “b” in “bitcoin”, marked x below. Text, edges and other logos stay outside it.

Stacked logo
Below this, switch to the horizontal wordmark.
Horizontal wordmark
Below this, use the Yaka symbol on its own.
Yaka symbol
The smallest size at which the mask's lines stay open. For app icons and favicons, use the දීප symbol.
06Misuse
Never do this
Use the files exactly as supplied. Never retype “bitcoin දීප” in a font: the දීප is custom lettering.









07Colour
Bitcoin orange leads
Orange carries the brand. Black and white are the grounds. The flame gradient belongs to the mask, and the four heritage colours belong to the secondary pattern. Copy any value in HEX, RGB or HSL.
The orange of the ₿ logo, named for Bitcoin's creator.
After the genesis block, where Bitcoin began.
After the 2008 Bitcoin whitepaper.
Grounds
Cold Storage Charcoal for cards and product, Paper Wallet Cream for decks and documents, Genesis Black for print and merchandise.
Cards, product. After the offline wallets that keep bitcoin safe.
Decks, documents. After keys printed on paper.
Print, merchandise. The same black as the primary.
Yaka flame gradient
Linear, bottom-left to top-right, six stops. For the mask and one hero moment at most. Never for text.
Heritage colours
The deep red of the Esala Perahera's festival cloth and the lion flag's field.
The dark canopy of Sinharaja, the island's last great rainforest.
The warm glow of Vesak lanterns and pandals.
The bright husk of the king coconut, sold at every roadside.
Heritage colours come from the Sri Lankan flag and colour the secondary pattern. Perahera Maroon also works as the headline colour on Paper Wallet Cream (9:1). Keep the other three inside the pattern.
Text on orange is black
Orange text needs a dark ground
Two oranges, never side by side
08Typography
Three typefaces, two scripts
Ubuntu for headlines, Nunito Sans for text, Noto Sans Sinhala for Sinhala. All three are free on Google Fonts. Ubuntu and Nunito Sans both appear in the master logo file.
Ubuntu
Headlines. Bold for titles; bold italic for hero lines only, echoing the slant of the wordmark.
Medium 500 · Bold 700 · Bold Italic
Get it on Google FontsNunito Sans
Body text, forms, captions. The slogan artwork uses its condensed italic.
Light 300 · Regular 400 · SemiBold 600 · Bold 700
Get it on Google FontsNoto Sans Sinhala
All Sinhala text. Give it more line height than Latin so vowel signs have room.
Regular 400 · Bold 700
Get it on Google FontsCampaign headlines may be set all lowercase in the display style, with “bitcoin” picked out in orange, as on the card backdrop: the first ever bitcoin card in sri lanka. In running text, write the name as Bitcoin Deepa. The lowercase “bitcoin දීප” is how the logo is drawn, not how the name is typed.
09Patterns
Primary pattern: ₿
A staggered field of ₿ marks in Bitcoin orange at about 10% strength. It is the brand's everyday background texture. It repeats on an even grid: ₿ marks every 86 units across and 44 down, each row shifted half a step, so the tile edges never show.
Keep it quiet so the logo and type sit on top without competing. The one exception is the notebook, where the ₿ marks run at full orange on black as a printed band that fades up the cover.
Secondary pattern: spiky tiles
The CeylonCash heritage pattern, redrawn for Bitcoin Deepa. Same sequence and the same four Lanka colours, but every tile has straight sides and corners that flare out into sharp spikes, echoing the points of the Yaka's crown.
Tall bars in Perahera Maroon, squares in Sinharaja Green, small tiles alternating Thambili Orange and Vesak Gold; every other band is shifted half a step. All tiles use the same spike size, so each shape is symmetrical, and the tile repeats without seams. Use it where the brand needs colour and energy: bands, borders, packaging, merchandise and event décor. Keep logos and text off it, or set them on a solid panel.
