Why is RGB code for green such a mess?

[Mike3456]

Logically, green should be #00FF00 because green is G in RGB where R is #FF0000 and B is #0000FF

However, all the RGB tables list green as #008000 while #00FF00 is actually lime

I played with a browser by setting background color using names and codes and clearly green=#008000 and lime=#00FF00

Some sources provide the codes incorrectly, e.g.

Wikipedia says green is #00FF00 at https://en.wikipedia.org/wiki/Green

It also says lime is #BFFF00 at https://en.wikipedia.org/wiki/Lime_(color)

These are the colors that were defined by the W3C and are the ones that browsers use: https://www.w3.org/wiki/CSS/Properties/color/keywords

 

I wouldn't rely on names for colors. They're vague and subjective. Use hexadecimal codes to ensure the color is exactly what you expected.

 

There are six pure colors:

 

Primary additive colors

Red #FF0000

Green #00FF00

Blue #0000FF

 

Primary subtractive colors

Cyan #00FFFF

Magenta #FF00FF

Yellow #FFFF00

 

For each of these colors you can change the value of FF change the brightness of those colors. #008000 is green and so is #00FF00. The only difference is the brightness of that green. Some people like to refer to really bright tones of green as "lime" but that's subjective.
