Hanukkah, Yule, Solstice, Mardis Gras, Kwanzaa, Shivratri, Purim, Easter, Samhain, Cinco De Mayo, Valentine's Day, Diwali &etc. If your palette/pattern celebrates a holiday - its food, customs, decorations, symbols - this is the place to give it a home.

The holiday doesn't need to be in the palette's title, but the palette should include a keyword for the applicable holiday.

Colors are welcome, too, if holiday-named.

Join in, make holiday palettes, invite all your friends, share the love. :)
