How to create an RGB image? - MATLAB Answers - MATLAB …
2017年5月26日 · What I have done thus far to create RGB images is to just load a white image and seperate the red green and blue components from this image and combine them in different ways to get different colors. No this feels kind of redundant because I keep thinking that MatLab must have a built-in RGB system in which you can just write a one line code ...

Each RGB triplet defines a color for 1 pixel of the image. An RGB triplet is a three-element vector that specifies the intensities of the red, green, and blue components of the color. The first page of the 3-D array contains the red components, the second page contains the green components, and the third page contains the blue components.
