If you want to select one of them, just press the numbers 1-9 depending on the position of the color samples (ex. green=1, dark blue=3, orange=9, etc.) and the color that you have currently selected will be displayed on the orange box right next to the color samples. And to change the brush size press the left and right arrow keys to go higher or lower
