Mixing colours
Press and hold X to activate
Mix Color mode. Now when you
click the colour swatch or any colour
pixel on the screen, the colour
spectrum will move towards the
selected colour. The more times you
click the new colour, the more tint
it gets from it. You can set the Mix
mode’s sensitivity in Preferences.

Colour sets
Every art program has the
ability to save colours and group
them into your own palettes,
and Rebelle is no different. In
the Color Set panel you can add
individual colours and create
palettes based on your own
requirements. Color Sets give
you quick access to your favourite
colours. An interesting feature is
that you can create a Color Set
from any imported image.5
Tracing colours
In Rebelle you can create paintings by tracing colours from a selected
image. This could be used as a foundation for your artwork when you want to
build it up, basing it on a particular photo. When you’re using Color Tracing,
the colour is automatically picked from the tracing layer.
Use PNG files if you
want to back up or
share your Color
Sets. You’ll find these
in Rebelle’s Library
in the Colors folder.
These PNG files are
created automatically
when you create a
new Color Set.A Color Set created from an image will contain a maximum of 16 colours. In the Color
Set menu click Create Color Set from Image to load the image and generate a Color Set.You can add or
remove colours,
and add or remove
Color Sets.Drag and drop an
image, or import it
by going to File>
Import... and it
opens as a new
layer. Select a layer
that you want to
trace, and set it as a
Trace Layer in the
Layer menu (a small
T will appear next
to the layer name).When you’re using Color Tracing, the
colour is applied for each stroke. This
means that each brush stroke picks the
colour pigment from the first “click” and
uses it until you do another click. Rebelle
doesn’t trace all colours from a reference
tracing layer during a single stroke.You can change the Tracing Color Sample

Switching to greyscale
is ideal for checking
whether colour values
in your artwork are right.
To do this, press G to
turn on Grayscale mode.The inner ring shows the chosen
colour, the lower half of the outer
ring the starting colour, and the
upper half the results of the mix.Set the sensitivity of Mix Color in
Preferences>Color. This determines
the number of steps between two
mixed colours. If sensitivity is low,
fewer steps (clicks) are required to
reach the second mixed colour.
When it’s high, it takes more clicks.Press X instead of clicking and you
can click and draw with your stylus.X
