Percent Red, Green, Blue, and Opacity Color Codes

This page demonstrates the percent representation of color of the form rgba(R%,G%,B%,a), where R, G, and B are the decimal values for the red, green, and blue values of the color on the range 0 to 100 and a is the opacity of the color (a = 0 = transparent; a = 1 = opaque). As of January 2009, the Mozilla and Google Chrome browsers display colors by this definition method. For example, the color with values 60% for red, 76% for green, and 88% for blue and which has an opacity of 0.5 (semi-transparent) is rgba(60%,76%,88%,0.5). This is just one of the ways you can define colors in HTML attributes and in Cascading Style Sheets; you can use a quick reference table to help you choose from among the many color tables available.

The color list below demonstrates these RBGA codes.
