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.

Features

Decreasing cognitive load by minimizing colors usage to highlight a code syntax

Additional distractions minimization with minimal theme

Contrast and eye-friendly. All colors tested by a Contrast Ratio and at least have value AA.

Supported: Javascript, Typescript, HTML, CSS, Go, C, C++, Java, Python (probably some other languages as well)

Main colors used for syntax highlighting

Luminosity Contrast Ratio greater than 7:1 for AAA, 4.5:1 for AA

Primary syntax color: #c6c8d0

Background: #161820
