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: 128/255 = 0.50196 → 0.215861  (((x + 0.055) / 1.055)^2.4)
B: 128/255 = 0.50196 → 0.215861  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.126878
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.170119
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.196799

3. cube root

l′ = ∛0.126878 = 0.502492
m′ = ∛0.170119 = 0.554095
s′ = ∛0.196799 = 0.581667

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.54312
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.08965
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.02363

5. Oklab → OKLCH

C = √(a² + b²) = 0.09271
H = atan2(b, a) = 194.769°
L = 0.54312

6. OKLCH

oklch(0.54312 0.09271 194.769)
rounded: oklch(0.543 0.093 194.8)
