Values are shown at full precision, so converting back gives exactly #ffa1ad. 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: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 161/255 = 0.63137 → 0.356400  (((x + 0.055) / 1.055)^2.4)
B: 173/255 = 0.67843 → 0.417885  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.624869
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.499384
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.451966

3. cube root

l′ = ∛0.624869 = 0.854928
m′ = ∛0.499384 = 0.793375
s′ = ∛0.451966 = 0.767424

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.80643
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.11006
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.02258

5. Oklab → OKLCH

C = √(a² + b²) = 0.11235
H = atan2(b, a) = 11.594°
L = 0.80643

6. OKLCH

oklch(0.80643 0.11235 11.594)
rounded: oklch(0.806 0.112 11.6)
