OKLCH to HEX: #FFFACD

Also known as: CSS lemonchiffon

oklch(0.97781 0.05822 102.156) → #FFFACD

Values are shown at full precision, so converting back gives exactly #fffacd. 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(0.97781 0.05822 102.156)
```

2. OKLCH → Oklab

a = C·cos H = -0.01226
b = C·sin H = 0.05691

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.985233
m′ = L − 0.1056·a − 0.0639·b = 0.975470
s′ = L − 0.0895·a − 1.2915·b = 0.905403

4. cube

l = 0.985233³ = 0.956351
m = 0.975470³ = 0.928200
s = 0.905403³ = 0.742207

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 1.000006
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.955975
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.610478

6. linear → sRGB, × 255

R = 1.00000 × 255 = 255.00 → 255
G = 0.98039 × 255 = 250.00 → 250
B = 0.80391 × 255 = 205.00 → 205

7. RGB → HEX
```
#FFFACD
```
