Values are shown at full precision, so converting back gives exactly #cbfbf1. 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: 203/255 = 0.79608 → 0.597202  (((x + 0.055) / 1.055)^2.4)
G: 251/255 = 0.98431 → 0.964686  (((x + 0.055) / 1.055)^2.4)
B: 241/255 = 0.94510 → 0.879622  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.808825
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.877679
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.878648

3. cube root

l′ = ∛0.808825 = 0.931719
m′ = ∛0.877679 = 0.957441
s′ = ∛0.878648 = 0.957793

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.95203
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.05072
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00095

5. Oklab → OKLCH

C = √(a² + b²) = 0.05073
H = atan2(b, a) = 181.074°
L = 0.95203

6. OKLCH

oklch(0.95203 0.05073 181.074)
rounded: oklch(0.952 0.051 181.1)
