First convert to an indexed image with uint8(). Then choose a colormap, then call ind2rgb().

hi sir, can you show the coding. let saya my coding is

B = dicomread('TRANSA001_CT025.dcm');

[Image Analyst]

% Convert RGB image to gray scale
grayImage = rgb2gray(B);
% Get color image "back":
% Nothing to do - you still have B (the original RGB image) so you're all set.
