Resistor colors

Question

My project is about how to detect color in MATLAB.
First, I have to take a photo of a resistor by webcam or camera.
Second, I have to detect the color of the resistor (RGB image) and calculate the value of it. Because there are 10 colors in a resistor, I don't know how to detect each of them.
Please help me. Thanks

Convert the 10 colors in RGB.
Here there is a list of common colors link[^].
A color can then be represended in a 3D domain where the 3 axes are R-G-B.
Plot in that domain also the point relatad to the unknown pixel...then you can recognise the right color computing the distance between this point to the other given 10.
