Step-by-step math

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

1. sRGB → linear

R: 124/255 = 0.48627 → 0.201556  (((x + 0.055) / 1.055)^2.4)
G: 109/255 = 0.42745 → 0.152926  (((x + 0.055) / 1.055)^2.4)
B: 103/255 = 0.40392 → 0.135633  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.172083
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.161374
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.146326

3. cube root

l′ = ∛0.172083 = 0.556219
m′ = ∛0.161374 = 0.544433
s′ = ∛0.146326 = 0.526956

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.54698
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01544
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01444

5. Oklab → OKLCH

C = √(a² + b²) = 0.02114
H = atan2(b, a) = 43.085°
L = 0.54698

6. OKLCH

oklch(0.54698 0.02114 43.085)
rounded: oklch(0.547 0.021 43.1)
