Use a pattern for task row shading

Can I shade task rows or cells with a pattern instead of a solid color?

Yes. Starting with version 2025, patterns can be used for task row and cell backgrounds.

Select the task rows to shade. To shade every row, start from the schedule's task row shading settings instead.
On the toolbar, click the arrow for More Task Row Options and choose Gridline/Shade.
Choose a pattern. The shade color becomes the pattern color, and the effects Target Color becomes the pattern's background color.
Click OK.
