feat(highlight): update default color scheme Problem: Default color scheme is suboptimal. Solution: Start using new color scheme. Introduce new `vim` color scheme for opt-in backward compatibility. ------ Main design ideas - Be "Neovim branded". - Be minimal for 256 colors with a bit more shades for true colors. - Be accessible through high enough contrast ratios. - Be suitable for dark and light backgrounds via exchange of dark and light palettes. ------ Palettes - Have dark and light variants. Implemented through exporeted `NvimDark` and `NvimLight` hex colors. - Palettes have 4 shades of grey for UI elements and 6 colors (red, yellow, green, cyan, blue, magenta). - Actual values are computed procedurally in Oklch color space based on a handful of hyperparameters. - Each color has a 256 colors variant with perceptually closest color. ------ Highlight groups Use: - Grey shades for general UI according to their design. - Bold text for keywords (`Statement` highlight group). This is an important choice to increase accessibility for people with color deficiencies, as it doesn't rely on actual color. - Green for strings, `DiffAdd` (as background), `DiagnosticOk`, and some minor text UI elements. - Cyan as main syntax color, i.e. for function usage (`Function` highlight group), `DiffText`, `DiagnosticInfo`, and some minor text UI elements. - Red to generally mean high user attention, i.e. errors; in particular for `ErrorMsg`, `DiffDelete`, `DiagnosticError`. - Yellow very sparingly only with true colors to mean mild user attention, i.e. warnings. That is, `DiagnosticWarn` and `WarningMsg`. - Blue very sparingly only with true colors as `DiagnosticHint` and some additional important syntax group (like `Identifier`). - Magenta very carefully (if at all). ------ Notes - To make tests work without relatively larege updates, each one is prepended with an equivalent of the call `:colorscheme vim`. Plus some tests which spawn new Neovim instances also now use 'vim' color scheme. In some cases tests are updated to fit new default color scheme. 2023-11-29 13:16:09 -07:00			`" Neovim color file`

feat(highlight): tweak default color scheme Problem: Updating default color scheme produced some feedback. Solution: Address the feedback. Outline of the changes: - Colors `Grey1` and `Grey2` are made a little bit more extreme (dark - darker, light - lighter) to increase overall contrast. - `gui` colors are treated as base with `cterm` colors falling back to using 0-15 colors which come from terminal emulator. - Update highlight group definition to not include attribute definition if it is intended to staty uncolored. - Tweak some specific highlight groups. - Add a list of Neovim specific highlight groups which are now defined differently in a breaking way. - Minor tweaks in several other places related to default color scheme. 2023-12-12 09:07:45 -07:00			" This is the default color scheme.
