Values are shown at full precision, so converting back gives exactly #f08080. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. sRGB → linear

R: 240/255 = 0.94118 → 0.871367  (((x + 0.055) / 1.055)^2.4)
G: 128/255 = 0.50196 → 0.215861  (((x + 0.055) / 1.055)^2.4)
B: 128/255 = 0.50196 → 0.215861  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.486074
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.354765
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.273743

3. cube root

l′ = ∛0.486074 = 0.786263
m′ = ∛0.354765 = 0.707913
s′ = ∛0.273743 = 0.649304

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.72464
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.12857
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.04943

5. Oklab → OKLCH

C = √(a² + b²) = 0.13774
H = atan2(b, a) = 21.029°
L = 0.72464

6. OKLCH

oklch(0.72464 0.13774 21.029)
rounded: oklch(0.725 0.138 21.0)
