Step-by-step math

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

1. input
```
oklch(0.84932 0.20734 128.850)
```

2. OKLCH → Oklab

a = C·cos H = -0.13006
b = C·sin H = 0.16147

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.832619
m′ = L − 0.1056·a − 0.0639·b = 0.852739
s′ = L − 0.0895·a − 1.2915·b = 0.652416

4. cube

l = 0.832619³ = 0.577216
m = 0.852739³ = 0.620080
s = 0.652416³ = 0.277699

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.366256
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.791311
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.035605

6. linear → sRGB, × 255

R = 0.63922 × 255 = 163.00 → 163
G = 0.90197 × 255 = 230.00 → 230
B = 0.20786 × 255 = 53.00 → 53

7. RGB → HEX
```
#A3E635
```
