Values are shown at full precision, so converting back gives exactly #b8e6fe. 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: 184/255 = 0.72157 → 0.479320  (((x + 0.055) / 1.055)^2.4)
G: 230/255 = 0.90196 → 0.791298  (((x + 0.055) / 1.055)^2.4)
B: 254/255 = 0.99608 → 0.991102  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.672973
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.746647
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.889622

3. cube root

l′ = ∛0.672973 = 0.876326
m′ = ∛0.746647 = 0.907204
s′ = ∛0.889622 = 0.961764

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.90048
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.03649
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.04492

5. Oklab → OKLCH

C = √(a² + b²) = 0.05788
H = atan2(b, a) = 230.911°
L = 0.90048

6. OKLCH

oklch(0.90048 0.05788 230.911)
rounded: oklch(0.900 0.058 230.9)
