Step-by-step math

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

1. sRGB → linear

R: 245/255 = 0.96078 → 0.913099  (((x + 0.055) / 1.055)^2.4)
G: 245/255 = 0.96078 → 0.913099  (((x + 0.055) / 1.055)^2.4)
B: 220/255 = 0.86275 → 0.715694  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.902943
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.891898
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.788738

3. cube root

l′ = ∛0.902943 = 0.966541
m′ = ∛0.891898 = 0.962583
s′ = ∛0.788738 = 0.923941

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.96357
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00958
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.03135

5. Oklab → OKLCH

C = √(a² + b²) = 0.03278
H = atan2(b, a) = 106.999°
L = 0.96357

6. OKLCH

oklch(0.96357 0.03278 106.999)
rounded: oklch(0.964 0.033 107.0)
