I'm trying to obtain the colour of a specific coordinate on an image. For example: X is an image with size width:300 and height:300. I would like to know the colour at x:10 and y:10 coordinate. I couldn't write any code because I don't know if this is even possible in matlab?

Thank you.

Is it a true RGB image or an index image mapped onto a colourmap?
