Step-by-step math

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

1. sRGB → linear

R: 112/255 = 0.43922 → 0.162029  (((x + 0.055) / 1.055)^2.4)
G: 8/255 = 0.03137 → 0.002428  (÷ 12.92)
B: 231/255 = 0.90588 → 0.799103  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.109205
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.121809
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.518409

3. cube root

l′ = ∛0.109205 = 0.477985
m′ = ∛0.121809 = 0.495708
s′ = ∛0.518409 = 0.803324

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.49073
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.10355
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.24922

5. Oklab → OKLCH

C = √(a² + b²) = 0.26988
H = atan2(b, a) = 292.563°
L = 0.49073

6. OKLCH

oklch(0.49073 0.26988 292.563)
rounded: oklch(0.491 0.270 292.6)
