New Protanopia & Deuteranopia colorblind themes for red/green color blindness are now available to all github.com users in a public beta. Based on customer feedback, the previous Colorblind theme has been split into two themes: a Protanopia & Deuteranopia colorblind theme, and a Tritanopia colorblind theme. This Protanopia & Deuteranopia colorblind theme is an update to the previous Colorblind themes. A Tritanopia colorblind theme is now also available in beta.
