Step-by-step math

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

1. sRGB → linear

R: 67/255 = 0.26275 → 0.056128  (((x + 0.055) / 1.055)^2.4)
G: 20/255 = 0.07843 → 0.006995  (((x + 0.055) / 1.055)^2.4)
B: 7/255 = 0.02745 → 0.002125  (÷ 12.92)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.026999
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.016884
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.008266

3. cube root

l′ = ∛0.026999 = 0.299995
m′ = ∛0.016884 = 0.256541
s′ = ∛0.008266 = 0.202189

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.26591
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.06146
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.04508

5. Oklab → OKLCH

C = √(a² + b²) = 0.07622
H = atan2(b, a) = 36.259°
L = 0.26591

6. OKLCH

oklch(0.26591 0.07622 36.259)
rounded: oklch(0.266 0.076 36.3)
