% Sample Solution
%

clear all
colormap('default');
load clown
flowers = imread('flowers.tif');

% Using clown...
image(X);
colormap(map);
pause
% 1. a) How many colors are there in clown? Ans: 81 Colors.
whos;			% Shows variable names and dimensions
size(map);		% 81x3 array. Number of rows indicates the number of
			% colors. There is one column for each RGB color component.
               
%    b) Display the color of the pixel at location 100x100.
image(X(100,100));
pause;

% Using Flowers...
colormap('default');	% Not necessary. But we'll do it for good measure.
image(flowers);
pause;
% 2. a) What are the RGB components of location 21x34?
r = flowers(21,34,1);	% Red (66)
g = flowers(21,34,2);	% Green (62)
b = flowers(21,34,3);	% Blue (97)

% 2. b) What color is this?
image(flowers(21,34,:));	% Dark green/blue.
