Step-by-step math

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

1. sRGB → linear

R: 95/255 = 0.37255 → 0.114435  (((x + 0.055) / 1.055)^2.4)
G: 158/255 = 0.61961 → 0.341914  (((x + 0.055) / 1.055)^2.4)
B: 160/255 = 0.62745 → 0.351533  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.248637
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.294744
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.327887

3. cube root

l′ = ∛0.248637 = 0.628814
m′ = ∛0.294744 = 0.665500
s′ = ∛0.327887 = 0.689564

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.65768
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.06172
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.02041

5. Oklab → OKLCH

C = √(a² + b²) = 0.06501
H = atan2(b, a) = 198.298°
L = 0.65768

6. OKLCH

oklch(0.65768 0.06501 198.298)
rounded: oklch(0.658 0.065 198.3)
