# GIMP logo: usage guidelines
## About this guide
This document explain how we should use GIMP logo
in the software, various
documents
or goodies. Other projects would usually
call such a document
"branding guidelines", except that
in GIMP community, we are not
into enforcing
strong branding guidelines
to others. So this document
is for ourselves mostly
and how we could use our logo
in and out
of GIMP.
While these guidelines apply
to us, we welcome anyone
else to make their own
version
of Wilber (the name
of our logo/mascot),
or even
modify our logo
for
their use
case if they wish so (our logo
is CC
by-sa
4.
0). Yet
when reusing
or
modifying our logo, we ask
of people not
to pretend
to be the GIMP team
if you
are not. We remind that impersonating others
is illegal
in most,
if not all,
countries.
## Main logo
Our current logo (`gimp-logo.svg`)
is flat
and simple
in its base
form. Unlike
our [previous version](../logo-
log.md), it doesn
't simulate depth:

An important part was keeping the recognizability
of Wilber, our mascot,
as well
as its smile
and friendliness. The goal
is to show both professionalism through
a new logo following nowadays trends
on minimalism,
while keeping the welcoming
side
of GIMP
as a community project rather than showing a corporate image.
The
5 colors used
in the main logo are:
1. Face
and lower part
of bristles: `#
8c8073`
2. Brush wood (handle): `#f2840`
3. Brush metal ring (ferrule): `#bbbbbb`
4. Top part
of brush hair (bristles), iris
and nose: `#
000000`
5. White
of Wilber eye
and light reflection (
on eye, nose): `#ffffff`
There
is some play with negative space
in the separation
between face
and nose.
This flat logo
is used
for desktop usage (menus, GNOME overview, title
bar, etc.).
### Usage
on similar
or unknown background
color (e.g.
in-Software)
When the background
color is unknown, it may end up being the same (
or
close)
color as Wilber itself (
or any other component
of the logo). Therefore
part
of the logo would blend
in with the background
and become invisible.
*Note: older versions of the previous logo used to have an [outlined
variant](
https://gitlab.gnome.org/GNOME/gimp/-/blob/f59f8a3df261567bd8c59f0f3d82fac0c9e38a3b/icons/Legacy/scalable/gimp-wilber-outline.svg)
for similar use cases. We don
't do this anymore. Having a shadow is much more
subtle
and works a lot better, even
in the extreme cases
where the background
color was the exact same
color as Wilber
's face, and even for smaller icon
sizes.
*
The typical
case for this
is when the logo
is used
in GIMP itself, since
the background
color of the application can be anything (it depends
on theme
colors
and third-party themes are allowed).
In such a
case, we use a variant
of the logo with a slight shadow
(`gimp-logo-shadow.svg`):

This
is the logo variant used
in GIMP
's About dialog or for the color icons of
GIMP.
### Bristles
color is meant
to change
The bristles
color is meant
to be interchangeable with
any color you
wish,
as though various paints was poured
on it.
This concept
is not currently used
in GIMP itself, nor
on any website, but this
is part
of the base design.
## Specific OS variants
Some OSes have specific design guidelines.
### macOS
macOS recommends
to embed icons
in a [rounded-rectangle
shape](
https://developer.apple.com/design/human-interface-guidelines/app-icons#m
acOS).

We also have an .icon version generated at build-time so in the final package
macOS can render different effects on the icon at runtime.
### Windows
Our main logo is used as-is on Windows. The logo has been designed to
make sure it renders well according to Microsoft's [Design guidelines
for Windows app
icons](https://learn.microsoft.com/en-us/windows/apps/design/style/iconography/app-icon-design)
too.
## Grayscale/unicolor variant
In pure grayscale, we provide a simpler unicolor variant
(`gimp-wilber-unicolor.svg`) which is preferred to making the main logo
grayscale:
<img style="background-color:white" src="gimp-logo-unicolor.svg" alt="GIMP's Unicolor logo" />
In this variant, the brush handle is simply removed, relying even more
on negative space design, giving some further elegance to the logo.
This logo can render pretty well on documents meant to be grayscale, both
printed documents or on screen, or on goodies printed with a single color.
It would also work very well for silk-screen printing.
*Note: since the unicolor logo is made to be recolored, this participated a lot
to the design of the eyes of Wilber (in all versions) which needed to not look
scary whatever the color variant. Nevertheless it is designed in particular for
being printed as a dark color on a light background.*
## Outline variant
This logo variant can be used typically for simple usages when you want
to display or print logo as outlines. Except for the bristles, the whole shape
is made of connected lines.
<img style="background-color:rgb(54,53,58)" src="gimp-logo-outline.svg" alt="Outline variant of GIMP logo" />
A very good example would be to create embroidered t-shirts with the
official logo.
## Icon
The logo is sometimes used as an icon for buttons, tabs or other parts of the
graphical interface.
### Color Icon
While our `Legacy` icon theme still uses the old Wilber, with
pixel-perfect variants for the smallest size and simplified vector
variant for intermediate sizes, our new logo being much simpler on
purpose, a single SVG is used for every size in the Color variant of the
`Default` icon theme.
In particular, we use the [main logo with shadow](#usage-on-similar-or-unknown-background-color-eg-in-software)
(`gimp-logo-shadow.svg`), so that the icon is always visible, whatever the
background color of the chosen theme.
As example of icon resizing:
* Color icon in 48×48: <img src="gimp-logo-shadow.svg" width="48" height="48"/>
* Color icon in 16×16: <img src="gimp-logo-shadow.svg" width="16" height="16"/>
### Symbolic Icon
The Symbolic variant uses a [dedicated symbolic version of the
logo](#grayscaleunicolor-variant) (`gimp-wilber-symbolic.svg`) for all sizes.
The symbolic variant is similar to the unicolor variant except that the eyes and
noses are colored with the `!important` property, ensuring that GIMP does not
recolor these parts of the design.
This way, we avoid the problem of Wilber seemingly looking up because the
highlight in the eyes becomes black and therefore looks like an iris.
As example of icon resizing:
* Symbolic icon in 48×48: <img src="gimp-wilber-symbolic.svg" width="48" height="48"/>
* Symbolic icon in 16×16: <img src="gimp-wilber-symbolic.svg" width="16" height="16"/>
### Wilber-eek
For errors in GIMP, we have a specific variant of the logo used as icon:
TODO
## Background (accent) color preferences
Freedesktop's AppStream specifications introduced the concept of ["brand
colors"](https://freedesktop.org/software/appstream/docs/chap-Metadata.html#tag-branding)
(also called "accent colors" sometimes), which are basically background colors
to be used behind the logo in either dark or light color schemes.
GNOME [announced making use](https://docs.flathub.org/blog/introducing-app-brand-colors/)
of this metadata in 2024 and Elementary OS and Pop!OS have been using this
concept [since longer](https://github.com/ximion/appstream/issues/187).
Other desktop environments or OSes may have similar concepts.
We don't have such accent colors defined for GIMP logo yet. TODO.
## Fun variations of the logo
We also make fun "development logo" variants (`gimp-devel-logo.svg`), which are
only used in unstable builds, as the name implies. Our current development logo
is:

It features rainbow colors being spilled on Wilber, like a scientific
experiment with colors, to represent the experimental side of Wilber. This logo
still features Wilber in gray with an older brush using negative space design,
as was originally proposed.
The development logo is swapped with the main logo in the About dialog
of unstable versions. It is not used as "app logo" in menus, title bars and so
on.
**Development logos are not to be considered "official".** They are only fun
experimental Wilbers, which can be swapped anytime as examples of variations of
Wilber.
*Note: currently the development logo only comes with a shadow since the
software is the only place we use it so far.*
