Sudan red can be used to test for lipids. It is soluble in lipids so it will turn the entire sample red.
Also, you can do the brown paper test. Put a few drops of the suspected lipid onto a brown paper bag. If the substance is a lipid, it will turn the spots translucent.

Brown Paper Test - Lipids can be tested with a brown paper. If it evaporates after being dropped on the paper, lipids are not present. If transparent spots appear on the paper, lipids are present.
Sudan IV Test - In the Sudan IV Test, dark red Sudan IV (a common dye) is added to a solution. If lipids are present, they will be dyed red.
