If you'd like to give art prints to someone whom you know appreciates abstract art, it's important to know the recipient's preferred styles as well as have a good understanding of their living space, favorite colors, and decor sensibilities. As with any other artwork, it's ideal to select work that complements your existing decor in both color, style, and composition.
If there are specific colors in your room that you'd like to emphasize, look for digital works which feature that color. For a harmonious look, pay attention to the lines (whether curvy or angular) in your artwork to see if they echo the lines in your room. For a more eclectic, eye-catching look, find work with colors that contrast with its surroundings, but in complementary hues.
