// This is my example picture. Now I want to make that red ball to be brown, green to be yellow and blue to be white. Notice that this picture also has antialiased lines.

//slide(x,y) means an array slide(from color,to color)

//these three lines make channel 0 (red channel) brown
//(172 red, 108 green and 48 blue equals brown)
slide(0,0) = 172
slide(0,1) = 108
slide(0,2) = 48
