Resources for CVD Friendliness

This is a list of things I found useful in making a universally accessible color palette. All pictures are clickable links. I don't own any of this information/images nor take credit for them. I just wanted to create this compilation as a resource for myself and anyone else that might find it useful. As a part of my placement at the Karstens Lab of OHSU we worked on creating the modified palette at the bottom of this page. It is an expansion of the Okabe Ito Palette.

Online CVD Simulators

These are colorblindness simulators that don't require code. You simply upload your image and select the type of colorblindness you want to emulate. Upload at your own risk, beware of images containing privileged information or PHI.

Coblis — Color Blindness Simulator

No images are uploaded to the server according to Colblindor

Only allows for viewing one simulation at a time

GUI CVD Emulator

Allows for viewing all simulations at once or each individually

Deletes uploaded image immediately after use

In the case of script or server fault image may not be deleted immediately, but nothing is kept longer than needed

Helpful Reading

Okabe Ito Paper

"How to make figures and presentations that are friendly to Colorblind people"

This paper is very helpful for understanding Color Vision Deficiency and improving CVD accessibility. It also makes recommendations on CVD checker software, resources, and tips.

colorblindr

R package created by Claus Wilk

This package allows you to simulate colorblindness and modify R figures. Images can even be converted to ggplot objects to view and modify colors. The functions for CVD simulation are simple to use, you just pass your existing figure in.

Color Pickers

Color Cop

This is a free app for windows that allows you to select colors and obtain the hexadecimal or hex codes. I found it very helpful. Click the link to the left to download.

Hexcolor

This is a free app for mac users that allows you to select colors and obtain the hex codes. I don't have experience using it but wanted to provide a potential option for mac users. Click the link to the left to download.

microshades R package

The microshades R package that includes carefully crafted palettes that improve CVD accessibility and may be applied to any plot. Additionally, there are functions to apply microshades palettes to microbiome data in a color-oriented orginazation. Click the microshades logo above to visit the microshades website.
