Step-by-step math

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

1. sRGB → linear

R: 217/255 = 0.85098 → 0.693872  (((x + 0.055) / 1.055)^2.4)
G: 119/255 = 0.46667 → 0.184475  (((x + 0.055) / 1.055)^2.4)
B: 6/255 = 0.02353 → 0.001821  (÷ 12.92)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.385062
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.272801
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.114388

3. cube root

l′ = ∛0.385062 = 0.727518
m′ = ∛0.272801 = 0.648558
s′ = ∛0.114388 = 0.485430

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.66584
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.08268
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.13396

5. Oklab → OKLCH

C = √(a² + b²) = 0.15742
H = atan2(b, a) = 58.318°
L = 0.66584

6. OKLCH

oklch(0.66584 0.15742 58.318)
rounded: oklch(0.666 0.157 58.3)
