Color Systems and Gradients in Graphics

Hexadecimal is a popular number system for setting colors in the graphics industry.
A hexadecimal color code consists of six characters.
The first two characters represent the amount of red.
The next two represent the amount of green.
The last two represent the amount of blue.
Example: The hexadecimal color code 000088 represents dark blue.
- 00 indicates no red.
- 00 indicates no green.
- 88 indicates a medium dark blue.
A warning may appear if the selected color is not in the gamut of colors available for the project, meaning the printed color may differ slightly.

Select the desired element (e.g., text) on the canvas.
Use the eyedropper tool to select the foreground color square in the properties panel.
The selected color will be applied to the element.
A check mark appears in the options bar to commit the change, or the change can be canceled.
Click the check mark to save the change.

Having two reference points for colors (foreground and background) ensures a consistent starting point for color schemes in photos, media, and graphic publications.
Consistency is crucial: You can use any method to set colors to match those in other projects.

Gradients involve a series of colors, transitioning from a start color to a finish color within a shape or selection.
