CAD tip # 13802:

First, you will need the .PAT pattern file - you can use, for example, a pattern like this with sufficiently dense lines of a monochrome "stripe" hatch:

*DUOCOL, Double color
45, 0, 0, 0, 19.05 
45, 1.1225325, 0, 0, 19.05
45, 2.2450650, 0, 0, 19.05
45, 3.3675975, 0, 0, 19.05
45, 4.4901300, 0, 0, 19.05
45, 5.6126625, 0, 0, 19.05
45, 6.7351950, 0, 0, 19.05
45, 7.8577275, 0, 0, 19.05
45, 8.9802600, 0, 0, 19.05 
45,10.1027925, 0, 0, 19.05 

The file is preset for metric units. Save these lines to the text file DUOCOL.PAT (the name is important) in the Support folder of your AutoCAD user profile, e.g. C:\Users\USERNAME\AppData\Roaming\Autodesk\AutoCAD 2024\R24.3\enu\Support\duocol.pat. Or download the ready-made file from duocol.pat.

Now create or edit a Hatch in your DWG drawing, set it to a user pattern called "DUOCOL" and then set the hatch color to yellow and the background color to red. That's all.
