L*a*b* Color Picker

To run this program:

1. Download the JAR file.
2. Run java -cp lab.jar LabPicker

How to use this program:
• Use the scrollwheel in the main area or the scroll bar at the left to change the intensity. Scroll up for brighter colors and down for darker colors.
• Click on a point to print out the L*a*b* and sRGB color coordinates and show the color in the bar across the bottom of the window.
• Drag the line in the main area to create an opponent color scale. The scale will be shown on the right side of the window.
• Clicking on the color scale on the right will print out 256 sRGB values for the color scale.
• Checking the box that says "Symmetric scale" will ensure that the scale is symmetric around the grey point.
• The dark grey background represents the colors that cannot be displayed on RGB monitors.

I got all my information from Wikipedia, so I make no guarantees for accuracy or correctness. Colors may be different depending on your monitor, too.

These are the Wikipedia articles I used:
• Lab color space
• sRGB color space
• CIE 1931 color space
• White point
