Step-by-step math

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

1. sRGB → linear

R: 210/255 = 0.82353 → 0.644480  (((x + 0.055) / 1.055)^2.4)
G: 180/255 = 0.70588 → 0.456411  (((x + 0.055) / 1.055)^2.4)
B: 140/255 = 0.54902 → 0.262251  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.523948
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.475411
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.350701

3. cube root

l′ = ∛0.523948 = 0.806175
m′ = ∛0.475411 = 0.780470
s′ = ∛0.350701 = 0.705200

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.78619
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01693
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.06154

5. Oklab → OKLCH

C = √(a² + b²) = 0.06382
H = atan2(b, a) = 74.619°
L = 0.78619

6. OKLCH

oklch(0.78619 0.06382 74.619)
rounded: oklch(0.786 0.064 74.6)
