Logo Tone
Ten famous brands, five picked each round. Recreate each brand's signature color from memory using hue, saturation, and brightness sliders. Scored by Delta E 2000 perceptual difference. Brand colors are more memorable than they seem — but they are often brighter, more saturated, or a different shade entirely from what most people picture when they think of the brand.

Why brand colors are deceptive
Brand colors are carefully designed to be distinctive but not extreme — they are the shade a brand has chosen after extensive design and testing, not the generic color their industry tends to use. Facebook's blue (#1877F2) is not "navy blue" or "royal blue" as most people picture it; it is a bright, slightly violet-leaning blue that looks much lighter on screen than in memory. Spotify's green (#1DB954) is brighter and more cyan-leaning than the "forest green" that first comes to mind. Starbucks' green (#00704A) is a specific deep emerald, not the dark forest green most people picture.
The game is calibrated to the brands' most commonly published primary brand colors, drawn from their public brand guidelines. It is a genuine test of how accurately you remember exact brand colors, not just their general hue families. Scores are usually in the 40–75 range — brand recognition is strong, but reproducing the exact shade is harder than people expect.
Tips for higher scores
- Match hue first — brand colors are often a different hue family than the "generic" color of their category. Facebook blue is more violet than expected; Spotify green is more cyan than expected.
- Brand colors are usually high-saturation (60–100%) and mid-to-high brightness (55–85%). They are intentionally vibrant, not muted.
- For tech brands (Apple, Google, Facebook), the "dominant" color is often not the whole logo — Apple's logo is black in its main form, Google's G is one color among four, Facebook is one blue among a family.
- Consumer brands (Coca-Cola, McDonald\'s, Starbucks) use more saturated colors than tech brands — the design logic is "be memorable on a shelf."
- When in doubt, err brighter and more saturated — brand colors are intentionally vivid, not muted.
Frequently asked questions
How does Logo Tone work?
Each round names a famous brand. You adjust hue, saturation, and brightness sliders to recreate their signature brand color from memory. Submit to reveal the correct color and see your Delta E 2000 score. Five rounds, 20 points per round, 100 points max. Random subset of brands each play.
What brands are included?
Ten: Starbucks, Coca-Cola, McDonald's, Apple, Facebook, Google, Spotify, Netflix, Amazon, and Twitter. Each has a widely-recognized signature color that most people feel they know — but reproducing the exact shade from memory is much harder than recognizing it when you see it.
Are these the official brand colors?
They are widely-published approximations of each brand's primary color, drawn from each brand's public brand guidelines. Brand colors are trademarks and officially specified by each brand — the hex values here are for the game and are not intended for any commercial use. Do not use these values as brand guidelines; refer to each brand's official brand resources for production work.
What is Delta E 2000?
Delta E 2000 (ΔE00) is the CIE standard for perceptual color difference. Lower is better: under 2 is imperceptibly close, under 5 is close, over 10 is clearly wrong. Delta E 2000 accounts for the fact that human eyes are more sensitive to some hue regions than others, so it produces more accurate scores than the older Delta E 1976 metric — especially for saturated blues like Facebook and Twitter, and for saturated greens like Spotify.
How are points calculated?
Twenty points per round maximum. Each unit of Delta E costs 2 points: ΔE 0 gives 20, ΔE 5 gives 10, ΔE 10 gives 0. Five rounds total, so 100 points is a perfect game. Most players score 40–75 — brand colors are memorable but not as easy to reproduce as people expect, especially the specific shades of major brands.
Why is Spotify green so hard?
Because Spotify's green (#1DB954) is noticeably brighter and more cyan-leaning than the "green" most people picture when they think of the brand. It reads as a bright, vibrant green on screen — but the hex value is a specific mid-tone that does not match the generic "Spotify green" memory most people carry. This is true for several other brands too: Facebook blue is much brighter than expected, Apple's logo is often remembered as silver but is officially black, and Twitter blue is a bright cerulean, not a navy.
