Values are shown at full precision, so converting back gives exactly #e12afb. 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. input
```
oklch(0.66636 0.29502 322.080)
```

2. OKLCH → Oklab

a = C·cos H = 0.23273
b = C·sin H = -0.18131

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.719474
m′ = L − 0.1056·a − 0.0639·b = 0.653370
s′ = L − 0.0895·a − 1.2915·b = 0.879690

4. cube

l = 0.719474³ = 0.372430
m = 0.653370³ = 0.278918
s = 0.879690³ = 0.680753

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.752954
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.023150
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.964705

6. linear → sRGB, × 255

R = 0.88236 × 255 = 225.00 → 225
G = 0.16469 × 255 = 42.00 → 42
B = 0.98432 × 255 = 251.00 → 251

7. RGB → HEX
```
#E12AFB
```
