Step-by-step math

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

1. sRGB → linear

R: 0/255 = 0.00000 → 0.000000  (÷ 12.92)
G: 120/255 = 0.47059 → 0.187821  (((x + 0.055) / 1.055)^2.4)
B: 111/255 = 0.43529 → 0.158961  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.108912
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.144921
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.153055

3. cube root

l′ = ∛0.108912 = 0.477557
m′ = ∛0.144921 = 0.525264
s′ = ∛0.153055 = 0.534912

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.51518
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.09002
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00904

5. Oklab → OKLCH

C = √(a² + b²) = 0.09047
H = atan2(b, a) = 185.733°
L = 0.51518

6. OKLCH

oklch(0.51518 0.09047 185.733)
rounded: oklch(0.515 0.090 185.7)
