(AI Quick Tip) Changing the Default Illustrator Artboard Background Color.
Changing the color of the artboard lets you view your document as it might appear when printed on colored paper. For example, if you draw a blue object on a yellow background, the object appears green. The simulation is only performed when the transparency grid is not shown.
# While the file is open, Go to File>Document Setup or Just hit “ctrl+alt+P”
# Now under the Transparency section, Select Simulate Colored Paper(Check it), Then click the top color swatch, and select a new color using the Color dialog box.
# And Say Thanks, Right here COMMENT and SHARE.
