How to check if a matrix falls in between other matrix values

Lets say I have a matrix that is for the range of my values for red

Red = [212 0 0; 255 34 255];

I need to determine if another matrix falls between these two rows.

M = [232 12 0];

How would I do this

Better yet, is there a way that MATLAB would know that the M matrix is red? Could I define a way to find red, orange, white, yellow, blue, and green?

Thanks

all(M >= Red(1,:) & M <= Red(2,:),3)

This would work for multiple rows of M matrix, producing one logical value per row of M.

There is no way that MATLAB would know that M is red except ways you (or someone) program. There is no built-in color identification method. Perception of color is individual, not universal, and there are no agreed boundaries for when something is or is not a particular color and not a different color.

Your Red would match [255 0 255] which few people would call red, being more likely to call magenta.
