Istanbul Theme for Rhino

Inspired by the soft daylight and sea breezes of Istanbul, this theme blends calm turquoise tones with warm historical accents to create a serene yet expressive coding environment. Light, airy backgrounds keep the editor clean and comfortable, while teals, aquas, and muted golden hues add clarity and focus to essential syntax elements.

A light theme from the Codigrate Cities collection, released 2026-01-03. Tags: Mediterranean, Historic, Airy.

Getting started on Rhino

1. Download the zip with the Download button. Inside are the Mac one-click app ( Codigrate <Name> Rhino Theme.app ) and the Windows color file ( Codigrate <Name>.ini ).
2. On a Mac, double-click the app and confirm you want to open it. It closes Rhino, applies the full theme ( viewport, toolbars, panels, tabs ), matches your macOS light or dark appearance to the theme, and reopens Rhino. The app is signed and notarized by Apple, so macOS opens it without a warning.
3. On Windows, run the OptionsImport command ( or Tools → Import Options… ) and choose the .ini file.
4. Tick Appearance, Grid and UiPaintColors and click Apply; the viewport and the toolbar and tab colors update at once.
5. Rhino draws a few controls with the system appearance, so keep Windows in light mode for a light theme and dark mode for a dark theme.
