@Jendrzych fixed a lot, and did a lot of work to bring us a new icon set for 2.8. However myself and many others believe the design goals behind them, namely their being mono-colour, are flawed and detract from the user experience in a desire to simplify things, and make the icons easier to create.
In an effort to give us an alternative to the mono-coloured icons Jendrzych made for 2.8, I’ve been adapting his icons to include a splash of colour, and an outline.
Update: Now complete and up to date (as of 09-04-2019)
For the sheet, please see the devtalk forum thread
- Icons get a black outline, if the interior is bright, or a light outline if the interior is dark. Sometimes both (a ‘shadow’ can be substituted if the shape/size can’t support an outline). This means all icons will work with any theme regardless of colour. It also slightly shrinks the icons, which overall adds more negative space between icon lists, but can make maintaining shape slightly difficult.
- In order to keep new icons relatively easy to create, these icons should match the look and style of icons that are purely white with a black outline.
- Colour should be added to aid in understanding icons, and distinguishing neighbouring icons. As such, not every icon needs colour.
- Colour-coding (that is, picking colours in an effort to organise and categorise related icons together) is secondary, as most places it adds little that the shape or context does not already handle. This also prevents us getting bogged down trying to over-categorise everything.
- Colours should be bright and not overly saturated, appearing more like a tinted white, this aids in matching coloured icons and non-coloured ones into a cohesive set. It also should keep icons reasonably theme-able.
