Color Handling 195

3D color editor
When editing RGB or CMYK colors the editor can be put into an advanced 3D mode that
displays colors in a color cube. Some people may prefer to work this way.

Specifying colors in the Color Editor

You can enter precise RGB (or HSV or
CMYK) color values in a number of
ways. The most common requirement
for web graphics is to enter a
hexadecimal RGB color.
You can do this with the color editor
showing either HSV colors (the default)
or showing RGB colors.
To select the RGB picker, right click on
the dialog and select RGB. This allows
you to enter RGB values as
percentages or 0-255 values.

Shows the expanded color editor, with the HSV
picker on the left, RGB picker on the right.

Percentages are used by default, but Designer Pro allows you to change which format is
used. To do this:

1. Display the UNITS tab of the OPTIONS dialog box (UTILITIES -> OPTIONS).
2. Click the appropriate radio button in the COLOR UNITS section.
3. Click OK to close the dialog box.
Limit to Browser palette

When clicked this button will shift the selected color to be one of the 216 common web
browser palette colors. This is a legacy system that is no longer particularly important or
relevant, as nearly all computers can display millions of colors, and there’s no benefit in
restricting web graphics to only this limited palette.

Colors on the screen and on the printer

One problem with computer screens is that their colors do not match the available colors
on a printer. Screens emit combinations of red, green, and blue. The brightness control
has a dramatic effect on displayed colors. Printed images reflect combinations of cyan,
magenta, yellow and black.
