Also known as: Tailwind mist-50

oklch(0.98657 0.00212 197.123) → #F9FBFB

Values are shown at full precision, so converting back gives exactly #f9fbfb. 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(0.98657 0.00212 197.123)
```

2. OKLCH → Oklab

a = C·cos H = -0.00203
b = C·sin H = -0.00062

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.985632
m′ = L − 0.1056·a − 0.0639·b = 0.986824
s′ = L − 0.0895·a − 1.2915·b = 0.987557

4. cube

l = 0.985632³ = 0.957513
m = 0.986824³ = 0.960990
s = 0.987557³ = 0.963135

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.947312
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.964667
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.964667

6. linear → sRGB, × 255

R = 0.97647 × 255 = 249.00 → 249
G = 0.98431 × 255 = 251.00 → 251
B = 0.98431 × 255 = 251.00 → 251

7. RGB → HEX
```
#F9FBFB
```
