I want to find specific colours in a image generally red green blue orange white black maroon etc. But there are alot of colors in a image. RGB has 256x256x256 range. The problem is I do not have any idea that what range of RGBs Combinations makes any specific colour. For Example, if I want to find black color I can try finding the pixels with RGB range within this [0, 0, 0], [10, 10, 10]. Any idea or trick ?
