Step-by-step math

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

1. sRGB → linear

R: 22/255 = 0.08627 → 0.008023  (((x + 0.055) / 1.055)^2.4)
G: 36/255 = 0.14118 → 0.017642  (((x + 0.055) / 1.055)^2.4)
B: 86/255 = 0.33725 → 0.093059  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.017557
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.023703
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.064304

3. cube root

l′ = ∛0.017557 = 0.259905
m′ = ∛0.023703 = 0.287256
s′ = ∛0.064304 = 0.400632

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.28104
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00301
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.09239

5. Oklab → OKLCH

C = √(a² + b²) = 0.09244
H = atan2(b, a) = 268.132°
L = 0.28104

6. OKLCH

oklch(0.28104 0.09244 268.132)
rounded: oklch(0.281 0.092 268.1)
