Ivory color values
Ivory
#FFFFF0
Black text reads best on this background, at 20.81:1.
Ivory is one of the 148 CSS named colors, and resolves to #FFFFF0 in every browser. In numbers that is rgb(255, 255, 240) and hsl(60, 100%, 97%). Perceptually it is a very light, near-neutral color: OKLCH puts its lightness at 100% and its chroma at 0.02. It carries almost no chroma, so it behaves as a neutral rather than as a hue, and belongs with the off-whites.
White text only reaches 1.01:1 here, so black text is the safer pairing at 20.81:1. Because it is this light, Ivory works best as a page or card background with dark text over it.
The closest CSS named colors to Ivory, measured with CIEDE2000, are FloralWhite (#FFFAF0), OldLace (#FDF5E6), Beige (#F5F5DC). If Ivory is not quite right, those are the nearest keywords to try before reaching for a custom value.
