It is always a problem for me to assign a certain color to a main hue. If you struggle also with this because of your color blindness, Color Name & Hue might help you. Try it out.
With this little tool you can either enter RGB (Red-Green-Blue) values, HSB (Hue-Saturation-Brightness) numbers or a hexadecimal code for a color, to find its closest match of a named color and its corresponding hue. It is also possible to just use the sliders to see how color hues are changing. The list of colors comprises 1640 different color names extracted from several sources on the web.
The color name is matched to one of the following main color hues: Red, Orange, Yellow, Green, Blue, Violet, Brown, Black, Grey, and White.
I always wanted to have such a tool because it’s fascinating for me to see matching color hues of colors I just can’t categorize. Finally I was inspired by Chirag Mehta and his toolName that Color. Many thanks to him. Color Name & Hue is just a little extension to his work. But nevertheless it took me a lot of time to match all those colors to their corresponding main color hues.
