I=imread(filename);
red=I(:,:,1);
green=I(:,:,2);
blue=I(:,:,3);
Ravg=(sum(sum(red)))./((size(red,1)).*(size(red,2)));
Gavg=(sum(sum(green)))./((size(green,1)).*(size(green,2)));
Bavg=(sum(sum(blue)))./((size(blue,1)).*(size(blue,2)));

What does "enhance" mean to you? Increase the saturation? If so, convert to HSV space with rgb2hsv() and multiply the second channel, the "S" channel, by some factor. See attached demo where I do that for the blue colored things.
Regarding your code, you could do it much simpler by
Ravg = mean2(red);
Gavg = mean2(green);
Bavg = mean2(blue);
