What does that mean? Why is your color image not already RGB? What color space is it in, and how did you create it in that color space? http://www.mathworks.com/matlabcentral/answers/728-how-do-i-write-a-good-question-for-matlab-answers

In a duplicate Question, the user posted
X=imread('images.jpg'); R = X(:,:,1); image(R), colormap([[0:1/255:1]', zeros(256,1), zeros(256,1)]), colorbar;
%Green Component G = X(:,:,2); figure; image(G), colormap([zeros(256,1),[0:1/255:1]', zeros(256,1)]), colorbar;
%Blue component B = X(:,:,3); figure; image(B), colormap([zeros(256,1), zeros(256,1), [0:1/255:1]']), colorbar;

X = im2double(imread('images.jpg'));
R = X(:,:,1);
G = X(:,:,2);
B = X(:,:,3);
z = zeros(size(R));
Rimg = cat(3, R, z, z);
Gimg = cat(3, z, G, z);
Bimg = cat(3, z, z, B);
L256 = linspace(0,1,256).';
z256 = zeros(256,1);
mapR = [L256, z256, z256];
mapG = [z256, L256, z256];
mapB = [z256, z256, L256];
figure; image(Rimg); colormap(mapR); colorbar();
figure; image(Gimg); colormap(mapG); colorbar();
figure; image(Bimg); colormap(mapB); colorbar();

I do not know what you mean by a "black gray image" ? Please capture a portion of the screen and post the image.
