Step-by-step math

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

1. sRGB → linear

R: 70/255 = 0.27451 → 0.061246  (((x + 0.055) / 1.055)^2.4)
G: 25/255 = 0.09804 → 0.009721  (((x + 0.055) / 1.055)^2.4)
B: 1/255 = 0.00392 → 0.000304  (÷ 12.92)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.030476
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.019628
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.008338

3. cube root

l′ = ∛0.030476 = 0.312359
m′ = ∛0.019628 = 0.269749
s′ = ∛0.008338 = 0.202778

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.27899
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.05411
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.05526

5. Oklab → OKLCH

C = √(a² + b²) = 0.07734
H = atan2(b, a) = 45.604°
L = 0.27899

6. OKLCH

oklch(0.27899 0.07734 45.604)
rounded: oklch(0.279 0.077 45.6)
