Step-by-step math

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

1. input
```
oklch(0.66713 0.16851 53.381)
```

2. OKLCH → Oklab

a = C·cos H = 0.10051
b = C·sin H = 0.13525

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.736155
m′ = L − 0.1056·a − 0.0639·b = 0.647883
s′ = L − 0.0895·a − 1.2915·b = 0.483463

4. cube

l = 0.736155³ = 0.398940
m = 0.647883³ = 0.271951
s = 0.483463³ = 0.113003

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.752942
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.165124
B = −0.0042·l − 0.7034·m + 1.7076·s = -0.000004

6. linear → sRGB, × 255

R = 0.88235 × 255 = 225.00 → 225
G = 0.44313 × 255 = 113.00 → 113
B = 0.00000 × 255 = 0.00 → 0

7. RGB → HEX
```
#E17100
```
