This application displays a large horizontal rectangle that runs the width of the screen. Below, ten small vertical rectangles span the screen. Finally, three horizontal color bars indicate values for blue, green, and red (RGB). Values are expressed as decimal (0-255) or hexadecimal (00-ff) based on the first menu selection.
To select a vertical bar to change, use the up navigation arrow to move to the color bars. Use the right navigation arrow to highlight a color bar. The large rectangle becomes the color of the selected bar.
Use the up or down selection arrows to choose the value to change (red, green, or blue). Use the left or right arrow keys to increase or decrease the selected value. The second menu item allows you to jump in increments of 4 (Fine) or 32 (coarse).
You can change the color on any or all of the vertical bars.
