Step-by-step math

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

1. sRGB → linear

R: 72/255 = 0.28235 → 0.064803  (((x + 0.055) / 1.055)^2.4)
G: 209/255 = 0.81961 → 0.637597  (((x + 0.055) / 1.055)^2.4)
B: 204/255 = 0.80000 → 0.603827  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.399742
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.512593
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.565744

3. cube root

l′ = ∛0.399742 = 0.736648
m′ = ∛0.512593 = 0.800309
s′ = ∛0.565744 = 0.827066

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.78680
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.11387
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.02329

5. Oklab → OKLCH

C = √(a² + b²) = 0.11622
H = atan2(b, a) = 191.558°
L = 0.78680

6. OKLCH

oklch(0.78680 0.11622 191.558)
rounded: oklch(0.787 0.116 191.6)
