Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. input
```
oklch(0.78530 0.10414 274.713)
```

2. OKLCH → Oklab

a = C·cos H = 0.00856
b = C·sin H = -0.10379

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.766293
m′ = L − 0.1056·a − 0.0639·b = 0.791024
s′ = L − 0.0895·a − 1.2915·b = 0.918575

4. cube

l = 0.766293³ = 0.449972
m = 0.791024³ = 0.494959
s = 0.918575³ = 0.775075

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.376257
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.456413
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.973478

6. linear → sRGB, × 255

R = 0.64706 × 255 = 165.00 → 165
G = 0.70588 × 255 = 180.00 → 180
B = 0.98825 × 255 = 252.00 → 252

7. RGB → HEX
```
#A5B4FC
```
