The dialog box for color selection can be opened by clicking a color field for font formatting, for background color selection and in a number of properties dialogs.
For color specification color spaces RGB and HSB are available for selection. Grab one of the small squares in the corners with the mouse and drag it to choose the corresponding color. Field Old / New color allows you to compare the new color to the old one. Clicking on old color causes it to be displayed in the corresponding object, if live update is supported by the object. This way, a before/after comparison can be made.
Selection of colors is particularly easy via the pipette. Click the pipette and the mouse pointer takes the form of a pipette. Use it to click the corresponding color on the screen or somewhere in the program window.
If you want to use your own standard colors for a project or want to use a particular color several times, you can define a Custom color. This is how you proceed:
Select a color so that it becomes visible in field Old / New color on the right.
Hold the Ctrl key pressed and click one of the squares in field Custom to save the corresponding color.
All colors saved under Custom can be directly selected by clicking them. This selection of colors will also be available when the dialog is opened again.
