Color is a Ruby library to provide RGB, CMYK, HSL, and other color space manipulation support to applications that require it. It provides optional named RGB colors that are commonly supported in HTML, SVG, and X11 applications. The Color library performs purely mathematical manipulation of the colors based on color theory without reference to device color profiles (such as sRGB or Adobe RGB). For most purposes, when working with RGB and HSL color spaces, this won't matter. Absolute color spaces (like CIE LAB and CIE XYZ) cannot be reliably converted to relative color spaces (like RGB) without color profiles. When necessary for conversions, Color provides D65 and D50 reference white values in Color::XYZ. Color 2.2 adds a minor feature where an RGB color created from values can silently inherit the `#name` of a predefined color if `color/rgb/colors` has already been loaded. It builds on the Color 2.0 major release, dropping support for all versions of Ruby prior to 3.2 as well as removing or renaming a number of features. The main breaking changes are: - Color classes are immutable Data objects; they are no longer mutable. - RGB named colors are no longer loaded on gem startup, but must be required explicitly (this is _not_ done via `autoload` because there are more than 100 named colors with spelling variations) with `require "color/rgb/colors"`. - Color palettes have been removed. - `Color::CSS` and `Color::CSS#[]` have been removed.

Glimmer DSL for Web (Ruby in the Browser Web Frontend Framework) enables building Web Frontends using Ruby in the Browser, as per Matz's recommendation in his RubyConf 2022 keynote speech to replace JavaScript with Ruby. It aims at providing the simplest, most intuitive, most straight-forward, and most productive frontend framework in existence. The framework follows the Ruby way (with DSLs and TIMTOWTDI) and the Rails way (Convention over Configuration) in building Isomorphic Ruby on Rails Applications. It provides a Ruby HTML DSL, which uniquely enables writing both structure code and logic code in one language. It supports both Unidirectional (One-Way) Data-Binding (using <=) and Bidirectional (Two-Way) Data-Binding (using <=>). Dynamic rendering (and re-rendering) of HTML content is also supported via Content Data-Binding. Modular design is supported with Glimmer Web Components, Component Slots, and Component Custom Event Listeners. And, a Ruby CSS DSL is supported with the included Glimmer DSL for CSS. Many samples are demonstrated in the Rails sample app (there is a very minimal Standalone [No Rails] sample app too). You can finally live in pure Rubyland on the Web in both the frontend and backend with Glimmer DSL for Web! This gem relies on Opal Ruby.
