Step-by-step math

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

1. sRGB → linear

R: 13/255 = 0.05098 → 0.004025  (((x + 0.055) / 1.055)^2.4)
G: 148/255 = 0.58039 → 0.296138  (((x + 0.055) / 1.055)^2.4)
B: 136/255 = 0.53333 → 0.246201  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.173154
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.228875
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.238885

3. cube root

l′ = ∛0.173154 = 0.557370
m′ = ∛0.228875 = 0.611692
s′ = ∛0.238885 = 0.620482

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.60022
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.10349
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00852

5. Oklab → OKLCH

C = √(a² + b²) = 0.10384
H = atan2(b, a) = 184.704°
L = 0.60022

6. OKLCH

oklch(0.60022 0.10384 184.704)
rounded: oklch(0.600 0.104 184.7)
