HEX to OKLCH: #FFDEAD

Also known as: CSS navajowhite

#FFDEAD → oklch(0.916 0.073 77.4)

Values are shown at full precision, so converting back gives exactly #ffdead. 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: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 222/255 = 0.87059 → 0.730461  (((x + 0.055) / 1.055)^2.4)
B: 173/255 = 0.67843 → 0.417885  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.825490
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.754007
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.557346

3. cube root

l′ = ∛0.825490 = 0.938074
m′ = ∛0.754007 = 0.910176
s′ = ∛0.557346 = 0.822953

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.91640
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01588
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.07126

5. Oklab → OKLCH

C = √(a² + b²) = 0.07301
H = atan2(b, a) = 77.436°
L = 0.91640

6. OKLCH

oklch(0.91640 0.07301 77.436)
rounded: oklch(0.916 0.073 77.4)
