Tints and shades

Lightness moves in ten-point steps while hue and saturation stay fixed, which keeps the colour recognisable in a scale. The last column is the ratio against white text, useful for deciding where a scale stops working as a background.

Step	Hex	HSL	vs white text
shade -30	`#c9b71a`	hsl(54, 77%, 45%)	2.04:1
shade -20	`#e4d232`	hsl(54, 77%, 55%)	1.55:1

Take the channels apart and the numbers hold together: 240, 230 and 140 average 203, the strongest channel is 240 and the weakest 140, and that span is what pushes saturation to 76.9% at hue 54.0° and lightness 74.5%. Luminance 0.7701 with perceived brightness 87.3 out of 100 is why the white ratio (1.28:1) and the black ratio (16.40:1) diverge by 15.12. Entry 19 of 69, it steps to #c9b71a at minus thirty and #ffffff at plus thirty.

Frequently asked questions

What text colour should sit on F0E68C?
Black gives 16.40:1 and white gives 1.28:1, so black wins at 16.40:1. That clears the 4.5:1 AA threshold for normal text and the 7:1 AAA threshold as well.

Do the CMYK numbers match a print workflow?
They are the naive conversion from RGB, which assumes no ink limit, no colour profile and no black generation strategy. Real print work needs a profile-aware conversion; the values here are the ones the converter reports and are best used as a starting point for a designer rather than a press-ready separations file.
