To determine if the color #FFC300 passes AAA contrast with #FEFEFE , we first need to calculate the contrast ratio between these two colors.

1. Hex to RGB conversion:
   • #FFC300 → RGB(255, 195, 0)
   • #FEFEFE → RGB(254, 254, 254)
2. Luminance calculation:
   • Luminance of #FFC300 :
     • R = 255, G = 195, B = 0
     • Luminance = 0.2126 * (R/255)^2.4 + 0.7152 * (G/255)^2.4 + 0.0722 * (B/255)^2.4
     • Luminance ≈ 0.2126 * 1 + 0.7152 * 0.724 + 0.0722 * 0
     • Luminance ≈ 0.2126 + 0.5174 + 0 = 0.730
   • Luminance of #FEFEFE :
     • R = 254, G = 254, B = 254
     • Luminance = 0.2126 * (254/255)^2.4 + 0.7152 * (254/255)^2.4 + 0.0722 * (254/255)^2.4
     • Luminance ≈ 0.2126 * 0.997 + 0.7152 * 0.997 + 0.0722 * 0.997
     • Luminance ≈ 0.2124 + 0.7135 + 0.0711 ≈ 0.997
3. Contrast ratio:
   • Contrast = (L1 + 0.05) / (L2 + 0.05)
   • Here, L1 (lighter) = 0.997 and L2 (darker) = 0.730
   • Contrast = (0.997 + 0.05) / (0.730 + 0.05) ≈ 1.047 / 0.780 ≈ 1.34
4. AAA Contrast requirements:
   • For normal text, the contrast ratio needs to be at least 4.5:1 for AA and 7:1 for AAA.
   • For large text (18pt bold or 14pt bold), the requirement is 3:1 for AA and 4.5:1 for AAA.

Since 1.34 is below the AA requirement, #FFC300 does not pass AAA contrast with #FEFEFE .

Now, for a color palette based on an energetic yellow like #FFC300 , here it is:

      "name": "Deep Charcoal",
      "hex_code": "
