Values are shown at full precision, so converting back gives exactly #7dd3fc. 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: 125/255 = 0.49020 → 0.205079  (((x + 0.055) / 1.055)^2.4)
G: 211/255 = 0.82745 → 0.651406  (((x + 0.055) / 1.055)^2.4)
B: 252/255 = 0.98824 → 0.973445  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.483988
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.591413
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.814872

3. cube root

l′ = ∛0.483988 = 0.785136
m′ = ∛0.591413 = 0.839390
s′ = ∛0.814872 = 0.934035

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.82759
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.06467
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.07794

5. Oklab → OKLCH

C = √(a² + b²) = 0.10128
H = atan2(b, a) = 230.318°
L = 0.82759

6. OKLCH

oklch(0.82759 0.10128 230.318)
rounded: oklch(0.828 0.101 230.3)
