Notes: Every pixel in an image (bitmap) is composed of three colors: Red, Green and Blue with degree of color from 0 to 255. White color is RGB

(255, 255, 255), Grey color is RGB(128, 128, 128), Black color is RGB(0, 0, 0), Yellow color is RGB(255, 255, 0), Red color is RBG(255, 0, 0), Green

color is (0, 255, 0) and Blue color is (0, 0, 255). By mixing the number, you can customize your own color scheme. Use the Pick Color tool

from

the Color Tool Box and place it on top of the image, it will show RGB number of that pixel, i.e. RGB(255, 83, 134). Same color in an image actually

covers a range of RGB colors. In order to change that color, you will need to find the range of RGB first. Use the Pick Color tool and place it all

range of colors to change. Use the Up/Down keys to move the color bar to make finer adjustment.
