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: 57/255 = 0.22353 → 0.040915  (((x + 0.055) / 1.055)^2.4)
B: 71/255 = 0.27843 → 0.063010  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.050433
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.047596
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.056630

3. cube root

l′ = ∛0.050433 = 0.369463
m′ = ∛0.047596 = 0.362402
s′ = ∛0.056630 = 0.384015

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.36380
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.02370
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.01729

5. Oklab → OKLCH

C = √(a² + b²) = 0.02934
H = atan2(b, a) = 323.885°
L = 0.36380

6. OKLCH

oklch(0.36380 0.02934 323.885)
rounded: oklch(0.364 0.029 323.9)
