Check out this app by SUNTORYCOLLECTION.COM. It’s cute, easy, and a way to test out if you like a color combination in a container garden. Just select the pot image, then click on the flower you like, drag it over to the center circle, add one or two more in adjacent circles, click OK.
This is how one turned out by selecting yellow and purple blooms (opposite on color wheel; complementary color) and an ivy for the spiller. It’s simple but it can work for immediate needs to test out combinations of colors.
