Step-by-step math

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

1. sRGB → linear

R: 153/255 = 0.60000 → 0.318547  (((x + 0.055) / 1.055)^2.4)
G: 50/255 = 0.19608 → 0.031896  (((x + 0.055) / 1.055)^2.4)
B: 204/255 = 0.80000 → 0.603827  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.179483
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.154062
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.417513

3. cube root

l′ = ∛0.179483 = 0.564081
m′ = ∛0.154062 = 0.536083
s′ = ∛0.417513 = 0.747406

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.54111
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.15060
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.17017

5. Oklab → OKLCH

C = √(a² + b²) = 0.22724
H = atan2(b, a) = 311.509°
L = 0.54111

6. OKLCH

oklch(0.54111 0.22724 311.509)
rounded: oklch(0.541 0.227 311.5)
