Conversion charts for Delta Ceramcoat and other brands of paint can be found online. Arts and crafts websites like NeedlePointers.com usually offer charts, as do online stores that sell art supplies such as DecoArt.com or Hofcraft.com.
The appearance of a particular color varies depending on the brand of paint. For example, one brand's shade of blue might be slightly darker than another. Paint conversion charts allow artists to compare colors from different brands and find the closest possible equivalent. For example, an artist who wants an exact match for orange paint from Brand X might have to mix red paint from Brand Y with yellow paint from Brand Z.
