Want to view Lab values in ColorThink?

A customer asked us recently:
In ColorThink, is there a way to manually enter individual Lab colors and plot them in the 2D or 3D graphs?

The answer is: Yes!

In the manual, in the section on the grapher, there is an example of a simple Lab color list you can create in seconds in any text program. You can just copy and paste this from the ColorWiki manual into your text program:

Or copy it from here:

Lab_L Lab_a Lab_b
91 -2 96
44 -29 2

Substitute the "91 -2 96" with Lab values of your own choosing, tab to create the space between numbers, make the list as long as you like, save it as a text file, and you can drag this file into the grapher or worksheet - and your Lab colors will be displayed.

You can also create these simple Lab color lists by bringing an image into the worksheet and clicking on it with the eye dropper tool. A list is automatically populated and you can Save List As... to export a text file or open it in the Grapher.
