Values are shown at full precision, so converting back gives exactly #ee82ee. 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: 238/255 = 0.93333 → 0.854993  (((x + 0.055) / 1.055)^2.4)
G: 130/255 = 0.50980 → 0.223228  (((x + 0.055) / 1.055)^2.4)
B: 238/255 = 0.93333 → 0.854993  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.516157
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.424951
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.677013

3. cube root

l′ = ∛0.516157 = 0.802159
m′ = ∛0.424951 = 0.751818
s′ = ∛0.677013 = 0.878076

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.76190
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.15647
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.10080

5. Oklab → OKLCH

C = √(a² + b²) = 0.18612
H = atan2(b, a) = 327.210°
L = 0.76190

6. OKLCH

oklch(0.76190 0.18612 327.210)
rounded: oklch(0.762 0.186 327.2)
