This document aim to provide standards propositions to unify the default brush preset icons of Krita , and ease the work of preset maintainers.
The default background is a neutral grey gradient, of 200px X 200px, without borders or decoractions
A preview icon is composed of 3 main blocks :
- Text/Picto area : a zone to write or use little picture
- Stroke area : a preview of the brush stroke itself
- Emblem/Icon : a visual to ease memorization of the brush
The brush preview feature a mini representation of the stroke. This stroke is colored with those color codes :
- Black is "normal"
- White is "erase" ( note : Checker pattern representing alpha too )
- Dark blue is color-smudge smearing mode ( note : little gradient in the stroke to a warmer color can helps )
- Purple is color-smudge dulling mode ( note : little gradient in the stroke to a warmer color can helps )
- light-blue for smudge-only
- ... FX presets can use distinct colors according to the fx-related resulting color
Note : The stroke can be exaggerated to boost the particular aspect of a brush.
Emblem / Icon
An icons/emblems pasted on the "brush preset preview" ease the selection for user with a visual memory. It also make the UI more user friendly
Icons can be vector, or 2D painted representation of tools or object.
To ease brush preset creation here is a pack of picture ready to customize with your stroke under :
text / Picto
A little optionnal text or logo that can be added on the top left corner. It might be related to the size, effect, or other factor The text can be written in any colors , but neutral are adviced ( white / grey / black ).
- Icon of a drop = the preset feels wet
- 'HB' ( text ) = the preset feels like a pencil 'HB'
- '0.1' (numeral) = the size of the preset is thin
- Icon of a star = the preset does Fx
- Icon of a warning = the preset is still experimental
As for any painting ressources, CC-Zero or Public Domain is adviced to let freedom of use to the end-users. You can't really ask a user to attribute your name each time one of your brush kit appears on a screenshot or is used into an artwork.
