@Zahir Elharith Mohammedelamein Ahmed - consider using rectangle to create multiple rectangles side-by-side. You can set the colour for each. For example,

rectangle('Position',[0,0,5,1],'FaceColor','b');
rectangle('Position',[5,0,3,1],'FaceColor', [0.5 0.5 0.1]);
xlim([-2 10])
ylim([-5 5])

The above code creates two rectangles of the same height but different lengths and colours.

Thank you very much. one more thing I forgot to mention is: what should I do if I want to make a for loop sayin if the number was (1) for example the rectangle should be colored blue...and so on..

You could try something like

myNumber = 1;
rectColor = '';
if myNumber == 1
    rectColor = 'b';
end
rectangle('Position',[0,0,5,1],'FaceColor', rectColor);
