Decimal Red, Green, Blue, and Opacity Color Codes
This page demonstrates the decimal 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 255 and a is the opacity of the color (a = 0 = transparent; a = 1 = opaque). As of May 2004, I don't know of any Web browser that displays colors by this definition method. For example, the color with decimal values 23 for red, 67 for green, and 88 for blue and which has an opacity of 0.5 (semi-transparent) is rgba(23,67,88,0.5). 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. Where the swatch square is blank, that means your browser does not display colors defined by this method.
