For any graphic designer or editor who often works with colours it is essential to have a program that indicates the code of the colour tone you wish to use. It is also important to have a converter among the different colour codes. Such a program that does both things is called KML Color Converter.
With KML Color Converter you can convert any colour code among the following formats: RGB, Hexa, Long VB, HTML, HSL e, CMV, CMYK or even KML from Google Earth (hence the program name).
KML Color Converter is totally free.
