We developed and use this tool at Great Sites. It allows for super simple color coordination.

Instructions

The colors in the GRID are PRESETS. Click on the button in the square with the PRESET you want to use.

• Click on the Background Button to select the background color for changing. (default)

  
  

• Click on the Foreground Button to select the foreground color for changing.

  
  

• The Red, Green and Blue color components range in value from 0-255 (or 0-ff in hex). By clicking on the buttons in the three color columns you can add or remove brightness from that color.

  
  

• The RANDOM button will choose random values for Red, Green and Blue components. We find that after a few clicks in a row we can 'accidentally' happen upon some great RGB combinations.
