col3x2 color dataset

Description

col3x2 color dataset.

Usage

data("col3x2")

Format

The format is: chr [1:6] "#1B9E77" "#D95F02" "#7570B3" "#66C2A5" "#FC8D62" "#8DA0CB"

Details

3x2 color scheme. These colors look like a 3x2 color array when run through the vischeck simulator to see how they look for the three most common color vision deficiencies: Deuteranope, Protanope, Tritanope.

References

About 10% of the population have color deficient vision. Your job is make your graphs legible to everyone. Download ImageJ from https://imagej.net/Downloads and VischeckJ from http://vischeck.com and follow the instructions in those sites. This program will allow you to simulate color deficient vision on your computer.

On my Mac, I need to doubleclick ij.jar to open the program. Then open the "Vischeck Panel" on the Plugins menu and navigate to a png file with the "File Open" menu. Click on each of the three types of color deficiency.
