A warm, minimalistic theme family for JetBrains IDEs.

Umber is built around warm, earthy tones that reduce eye fatigue during long coding sessions.

• Muted keywords — keywords are desaturated so they don't compete with identifiers and values
• Soft accent — functions and links use a calm steel blue (#6699CC) as the primary accent
• Warm surfaces — every UI surface (sidebar, tabs, popups, status bar) uses tinted backgrounds instead of neutral greys
• Light variant — uses background highlighting to mark syntax regions rather than coloring text, inspired by the Alabaster approach

• WCAG AA contrast: all syntax tokens maintain a minimum 4.5:1 contrast ratio against their background, per WCAG 2.1 SC 1.4.3
• Colorblind-safe: the palette relies on a blue vs warm/amber axis rather than red vs green, and errors are indicated by underlines (not color alone), per WCAG 2.1 SC 1.4.1

Specifically tuned for TypeScript and Go with dedicated token colors for language-specific constructs.

Solid defaults for: JSON, YAML, CSS, HTML, Markdown.
