Step-by-step math

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

1. sRGB → linear

R: 219/255 = 0.85882 → 0.708376  (((x + 0.055) / 1.055)^2.4)
G: 39/255 = 0.15294 → 0.020289  (((x + 0.055) / 1.055)^2.4)
B: 119/255 = 0.46667 → 0.184475  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.312380
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.183730
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.184482

3. cube root

l′ = ∛0.312380 = 0.678517
m′ = ∛0.183730 = 0.568495
s′ = ∛0.184482 = 0.569270

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.59165
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.21797
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.00222

5. Oklab → OKLCH

C = √(a² + b²) = 0.21798
H = atan2(b, a) = 0.584°
L = 0.59165

6. OKLCH

oklch(0.59165 0.21798 0.584)
rounded: oklch(0.592 0.218 0.6)
