Step-by-step math

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

1. sRGB → linear

R: 147/255 = 0.57647 → 0.291771  (((x + 0.055) / 1.055)^2.4)
G: 197/255 = 0.77255 → 0.558340  (((x + 0.055) / 1.055)^2.4)
B: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.470263
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.547380
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.801856

3. cube root

l′ = ∛0.470263 = 0.777643
m′ = ∛0.547380 = 0.818018
s′ = ∛0.801856 = 0.929035

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.80907
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.02984
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.09082

5. Oklab → OKLCH

C = √(a² + b²) = 0.09560
H = atan2(b, a) = 251.813°
L = 0.80907

6. OKLCH

oklch(0.80907 0.09560 251.813)
rounded: oklch(0.809 0.096 251.8)
