# MATLAB: How to figure a colour based on a matrice of 1-by-3

imageimage processingMATLAB

This is my code:
%%In this part we just find the coordinates of the required coloursim = imread('Lighthouse.jpg');n = 4;figure, imshow(im)[x,y] = ginput(n);x = floor(x);y = floor(y);%colour(length(x),3);for i=1:length(x)      for j=1:3          colour(i,j) = im(y(i),x(i),j);      endendimage(colour)
when I run it, and slect a point on the image it doesn't show me the colour I selected!! it figures a red colour!! why is that? the variable colour is [195,213,223]
how can I visualize that RGB colour?

im = imread('peppers.png');n = 4;figure, imshow(im)[x,y] = ginput(n);x = floor(x);y = floor(y);%colour(length(x),3);colour = zeros(length(x), 1, 3, 'uint8');for i=1:length(x)  for j=1:3    colour(i,1, j) = im(y(i),x(i),j);  endendimage(colour)
