Bold, vibrant and friendly color is one cornerstone of Gatsby’s design. It distinguishes our brand and helps us to create consistent experiences and meaningful expressions across marketing and products.
Our color palette includes primary and secondary colors that can be used for interfaces as well as illustrations.
We are committed to complying with WCAG 2.0 AA standard contrast ratios. To do this, we choose primary, secondary and neutral colors that support usability. This ensures sufficient color contrast between elements so that users with low vision can see and use our products.
There is an equation provided by the WCAG (Web Content Accessibility Guidelines) that determines these two values.
The equation outputs a number between 0 and 21, with 21 being the highest amount of contrast—think black text and a white background—and 0 being no contrast—white on white.
The output of contrast between any two colors will fall somewhere on the spectrum between 0 – 21. That's where the scores are derived from.
There are technically 5 scores.

The most common form is red-green color blindness, followed by blue-yellow color blindness and total color blindness. Red-green color blindness affects up to 8% of males and 0.5% of females. Ensure that adjacent color shades are distinguishable for color blind people. Use a color blindness analyzer to confirm your choices.
