Step-by-step math

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

1. sRGB → linear

R: 0/255 = 0.00000 → 0.000000  (÷ 12.92)
G: 117/255 = 0.45882 → 0.177888  (((x + 0.055) / 1.055)^2.4)
B: 149/255 = 0.58431 → 0.300544  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.110869
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.153366
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.239451

3. cube root

l′ = ∛0.110869 = 0.480401
m′ = ∛0.153366 = 0.535274
s′ = ∛0.239451 = 0.620972

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.52338
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.06993
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.07072

5. Oklab → OKLCH

C = √(a² + b²) = 0.09946
H = atan2(b, a) = 225.325°
L = 0.52338

6. OKLCH

oklch(0.52338 0.09946 225.325)
rounded: oklch(0.523 0.099 225.3)
