color symbolism in the hawthorne
I found a chart below for color symbolism from the University of Nebraska at Omaha. I found it by Googling color symbolism. It's ok to use websites from universities, museums, etc (unless your instructor tells you differently).
Also below is a link from Western Oregon University about color symbolism in Hinduism.
If you go to the Databases by Subject LibGuide below and click on the Fine Arts tab, and then click on the EBSCO: Academic Search Complete link, you can search DE "SYMBOLISM of colors". That is a subject search. Use the limiters on the left for full text, publication date, etc.
You can also click on the EBSCO: MasterFile link in the same section, and conduct the same search.
