Also known as: Tailwind slate-300

oklch(0.86855 0.02161 252.514) → #CAD5E2

Values are shown at full precision, so converting back gives exactly #cad5e2. 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(0.86855 0.02161 252.514)
```

2. OKLCH → Oklab

a = C·cos H = -0.00649
b = C·sin H = -0.02061

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.861528
m′ = L − 0.1056·a − 0.0639·b = 0.870552
s′ = L − 0.0895·a − 1.2915·b = 0.895750

4. cube

l = 0.861528³ = 0.639453
m = 0.870552³ = 0.659756
s = 0.895750³ = 0.718722

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.590606
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.665383
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.760532

6. linear → sRGB, × 255

R = 0.79215 × 255 = 202.00 → 202
G = 0.83529 × 255 = 213.00 → 213
B = 0.88628 × 255 = 226.00 → 226

7. RGB → HEX
```
#CAD5E2
```
