We ran across these relay race ideas, and thought, Wow! The Golf Ball Race would be a great one to modify TO PRACTICE SPANISH COLORS. Here is how you would change it:
Instead of golf balls, substitute with colored jelly beans or other small colored items to put on a spoon. Then have one person be the color caller for each team with a list of colors in Spanish. The caller says a color in Spanish to the teammate who is up, and that person must go get the color and bring it back on the spoon. The team that gets through all the colors first wins.
