HEX to OKLCH: #FAEBD7

Also known as: CSS antiquewhite

#FAEBD7 → oklch(0.947 0.031 75.2)

Values are shown at full precision, so converting back gives exactly #faebd7. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. sRGB → linear

R: 250/255 = 0.98039 → 0.955973  (((x + 0.055) / 1.055)^2.4)
G: 235/255 = 0.92157 → 0.830770  (((x + 0.055) / 1.055)^2.4)
B: 215/255 = 0.84314 → 0.679542  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.874601
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.841060
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.746556

3. cube root

l′ = ∛0.874601 = 0.956320
m′ = ∛0.841060 = 0.943935
s′ = ∛0.746556 = 0.907167

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.94669
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00793
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.03005

5. Oklab → OKLCH

C = √(a² + b²) = 0.03108
H = atan2(b, a) = 75.219°
L = 0.94669

6. OKLCH

oklch(0.94669 0.03108 75.219)
rounded: oklch(0.947 0.031 75.2)
