Bitcoin Deepa logo with the slogan Pearl of Satoshi

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.

bitcoin

Set in lowercase, bold and slanted forward. It names the product plainly, in the world's language for it.

දීප

Deepa, “island”. Custom Sinhala lettering in Bitcoin orange. It puts Sri Lanka inside the name.

Pearl of Satoshi

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.

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.

Large-glyph icon

48px and below

Standard: the glyph fills about half the tile, leaving room for the masks phones apply. Large glyph: tighter margins, for favicons, browser tabs and notification badges, where every pixel of glyph counts.

Light and dark appearance

Light app iconLight small icon

Light

Orange glyph on a white tile. The default icon, and the one for light-mode home screens and light browser tabs.

Dark app iconDark small icon

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.

Masks and safe zone

iOS rounded square
Android circle
Android squircle

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

The glyph is always #F8931A, on #FFFFFF (light) or Cold Storage Charcoal #1D1E1D (dark). No orange tile, no gradient.

Nothing else on it

No wordmark, no ₿ coin, no Yaka, no badge or border. The app name appears under the icon on its own.

Why not the Yaka

At 32px the mask turns into a smudge. The Yaka stays the brand symbol everywhere there is room for it.Yaka mask at 32 pixelsDeepa icon at 32 pixels

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.

Below this, switch to the horizontal wordmark.

Horizontal wordmark

Below this, use the Yaka symbol on its own.

48px15mm print

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.

Stretch or squash it.
Rotate or re-slant it.
Change its colours.
Put the full-colour logo on orange.
Use the black version on dark grounds.
Add shadows, glows or outlines.
Place it on the spiky-tile pattern. (The faint ₿ pattern is fine.)
Rearrange the mask and wordmark.

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.

Satoshi Orange
#F8931APrimary

The orange of the ₿ logo, named for Bitcoin's creator.

Genesis Black
#000000Ground, wordmark

After the genesis block, where Bitcoin began.

Whitepaper White
#FFFFFFGround, wordmark

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.

Cold Storage Charcoal
#1D1E1D

Cards, product. After the offline wallets that keep bitcoin safe.

Paper Wallet Cream
#FFFCFA

Decks, documents. After keys printed on paper.

Genesis Black
#000000

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

Perahera Maroon
#8D183A

The deep red of the Esala Perahera's festival cloth and the lion flag's field.

Sinharaja Green
#00544F

The dark canopy of Sinharaja, the island's last great rainforest.

Vesak Gold
#FFBE2B

The warm glow of Vesak lanterns and pandals.

Thambili Orange
#EA7400

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

Black on orange reads 9.2:1. White on orange fails, so never use it for text.Buy Bitcoin9.2:1

Orange text needs a dark ground

Orange on white reads only 2.3:1. On white, set orange text in the darker #9A4C00.On black9.2:1On white6.2:1

Two oranges, never side by side

Satoshi Orange and Thambili Orange are close but different. Keep Thambili Orange inside the pattern.

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.

Headlines. Bold for titles; bold italic for hero lines only, echoing the slant of the wordmark.

Campaign 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.

On Black
On Warm White

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.

On white
On Cold Storage Charcoal

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.

10Voice

How we sound

Plain

Explain Bitcoin in everyday words. Introduce a technical term only with a short explanation.

Bilingual

Sinhala and English stand side by side as equals. When space allows, give both.

Proud of the island

The mask, the flag colours and the slogan already say this is Sri Lankan Bitcoin. The copy can say it too, without clichés.
