Step-by-step math

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

1. sRGB → linear

R: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 228/255 = 0.89412 → 0.775822  (((x + 0.055) / 1.055)^2.4)
B: 196/255 = 0.76863 → 0.552011  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.856719
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.799290
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.654622

3. cube root

l′ = ∛0.856719 = 0.949758
m′ = ∛0.799290 = 0.928043
s′ = ∛0.654622 = 0.868287

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.93286
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01603
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.04889

5. Oklab → OKLCH

C = √(a² + b²) = 0.05145
H = atan2(b, a) = 71.849°
L = 0.93286

6. OKLCH

oklch(0.93286 0.05145 71.849)
rounded: oklch(0.933 0.051 71.8)
