RDCD theme is a reduced color scheme for syntax highlighting and minimal theme for VSCode
Why to reduce color usage
Some elements of the code that can add visual noise are using only one color with lower luminosity than context meaningful parts because additional colors add additional cognitive work to process. With RDCD syntax, just two colors are used + one additional color for comments and unused instances.
All signals (errors, modifications, alerts, etc.) are using colors with intensive luminosity to make it easily visible.
