Step-by-step math

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

1. sRGB → linear

R: 143/255 = 0.56078 → 0.274677  (((x + 0.055) / 1.055)^2.4)
G: 188/255 = 0.73725 → 0.502886  (((x + 0.055) / 1.055)^2.4)
B: 143/255 = 0.56078 → 0.274677  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.397073
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.430019
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.338968

3. cube root

l′ = ∛0.397073 = 0.735005
m′ = ∛0.430019 = 0.754795
s′ = ∛0.338968 = 0.697246

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.75086
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.06508
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.04603

5. Oklab → OKLCH

C = √(a² + b²) = 0.07971
H = atan2(b, a) = 144.730°
L = 0.75086

6. OKLCH

oklch(0.75086 0.07971 144.730)
rounded: oklch(0.751 0.080 144.7)
