Each developer has his or her own preference for how they like to reference colors in their CSS code. Some developers are partial to using hex codes (a six character code of letters and numbers preceded by a #), while others prefer to use rgb codes (rgb codes are made up of three number values to indicate the amount of red, green, and blue in a color). The problem with the fact that both hex and rgb codes are widely used is that there’s no easy or simple way to convert one type of color code to the other.
Luckily for us developers, web apps exist that will quickly convert hex to rgb and vice versa in a matter of seconds (we didn’t include any rgba converters on this list, but remember — rgba is the same color as rgb, just with the option for transparency. To turn rgb into rgba you’ll just need to write rgba instead of rgb, then add a fourth value to the end of your list of rgb values in the parentheses. The value should be between 0 and 1 depending on how opaque you want your color to be. 1 for completely opaque, 0 for completely transparent). Take a look at the following list of platforms that will perform this conversion quickly and easily:
