Existing colors can be edited. Double click on the relevant list
entry and you will see the following dialog:
Here you can rename the color, even by using its current color
values. You can also label it, e.g. to group certain colors. The label
color of a color will be shown in the Kleur-infovenster color list
afterwards.

You can assign a color to a certain color model. iCalamus
supports the following color models:
- CMYK
-
This is the color model of your choice whenever you want to
create documents for offset printing and want to use pre-separated
colors. CMYK stands for Cyan, Magenta, Yellow, and Key (CMYK is often
pronounced
Smike
). The color values in the CMYK color model
usually have 8 bits of color information per color channel, which
means 32 bits per color dot in an image.
- RGB
-
The RGB color model offers unseparated colors and is the main
color model in the world of computers. Almost all color input devices
(like scanners and digital cameras) as well as monitors use this color
model. RGB stands for Red, Green, Blue. The color values in the RGB
color model usually have 8 bits of color information per color
channel, which means up to 24 bits per dot in an image, or 16.7
million color choices.
- Grijs
-
The Graytone color model only uses 8 bits of color information
(or 256 gray tones) per dot in an image.

Here you can select a color space which then will be used for
mapping the color model to a certain device or system. A color model
without any associated color space is a more or less arbitrary,
theoretical color system without any relation to reality. In reality,
you will not always be able to reproduce all given colors of a color
model. Therefore, pre-defined color spaces help adjusting or
calibrating your color model for a target purpose. The available color
spaces depend on your chosen color model.
- Webkleuren
-
The small # field below the color sliders shows the web color
value of the current color. Web colors are used to represent colors in
HTML pages in the web. Web colors are basically defined in RGB and are
written in hexadecimal format, using number values from 0 to F
(F = 15). #000000 here means R0 G0 B0 (Black), #FFFFFF means
R255 G255 B255 (White).
To get more detailed information about web colors, see, for example,
Wikipedia.
Hint: Please keep in mind that web
colors are always RGB, even if you have chosen the CMYK color model
for the current color. If you e.g. create new colors using web color
values, but choose the CMYK color model, the color results may differ
from what you expected.
