The purple and teal combination is one that is perfect for someone who is not afraid to make a bold decor statement. It is perfect for kids and teens, since they tend to like bright colors, but that doesn’t mean it can’t work in an adult’s bedroom. The important thing is to consider what other colors are presently in the bedroom, mainly on the walls and carpeting. In other words, the colors that take up the most amount of space. If those colors are already bright, the addition of bright bedding may be too much. It may be wiser to stick with neutral colors for the walls and floor coverings.
One of the subtler examples I could find:

In terms of accessories such as throw pillows and rugs, you may also want to stick with muted colors. The bedding will likely be the focal point, since your bed is probably the biggest piece of furniture in the room. Because of this, whatever colors you choose for your bedding can end up being the room’s predominant colors. You don’t want your rugs and pillows to clash with your bedding, so pick these carefully: either go for shades of teal and purple, or stick to cream, beige or ivory. Colors that will not grab the attention.
