The leaves of winged burning bush (Euonymus alatus) turn bright red in full sun, or white in full shade. This photo shows the gradation on a single bush.
Please, by the way, don't plant this species, and if you have it, consider replacing it with some less invasive colorful shrub. It can be pretty, but winged burning bush has proven highly invasive in local woodlands, outcompeting native shrubs and shading out spring wildflowers.
This maple on Aiken may have gotten a farmer's tan on the top because the lower half is shaded by the tree across the street, and thus is slower to change color.
