Step-by-step math

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

1. sRGB → linear

R: 50/255 = 0.19608 → 0.031896  (((x + 0.055) / 1.055)^2.4)
G: 205/255 = 0.80392 → 0.610496  (((x + 0.055) / 1.055)^2.4)
B: 50/255 = 0.19608 → 0.031896  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.342218
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.425748
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.194898

3. cube root

l′ = ∛0.342218 = 0.699467
m′ = ∛0.425748 = 0.752288
s′ = ∛0.194898 = 0.579788

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.74187
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.18221
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.13813

5. Oklab → OKLCH

C = √(a² + b²) = 0.22865
H = atan2(b, a) = 142.835°
L = 0.74187

6. OKLCH

oklch(0.74187 0.22865 142.835)
rounded: oklch(0.742 0.229 142.8)
