Step-by-step math

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

1. sRGB → linear

R: 237/255 = 0.92941 → 0.846873  (((x + 0.055) / 1.055)^2.4)
G: 106/255 = 0.41569 → 0.144128  (((x + 0.055) / 1.055)^2.4)
B: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.477846
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.384961
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.745363

3. cube root

l′ = ∛0.477846 = 0.781801
m′ = ∛0.384961 = 0.727454
s′ = ∛0.745363 = 0.906684

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.73816
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.18826
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.14353

5. Oklab → OKLCH

C = √(a² + b²) = 0.23673
H = atan2(b, a) = 322.677°
L = 0.73816

6. OKLCH

oklch(0.73816 0.23673 322.677)
rounded: oklch(0.738 0.237 322.7)
