Step-by-step math

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

1. sRGB → linear

R: 94/255 = 0.36863 → 0.111932  (((x + 0.055) / 1.055)^2.4)
G: 233/255 = 0.91373 → 0.814847  (((x + 0.055) / 1.055)^2.4)
B: 181/255 = 0.70980 → 0.462077  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.506942
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.628010
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.530540

3. cube root

l′ = ∛0.506942 = 0.797357
m′ = ∛0.628010 = 0.856358
s′ = ∛0.530540 = 0.809542

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.84413
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.13780
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.03633

5. Oklab → OKLCH

C = √(a² + b²) = 0.14251
H = atan2(b, a) = 165.230°
L = 0.84413

6. OKLCH

oklch(0.84413 0.14251 165.230)
rounded: oklch(0.844 0.143 165.2)
