Choose a color of paint that complements your contemporary room decor. Although there are no established contemporary colors, some shades provide a more modern-day feel than others. Try a high-gloss black, metallic silver, fresh white or even primary red as a contemporary style choice. Use this color for the window trim, sill and seat, if applicable.
Remove all current window treatments and furniture from the bay window. Paint the trim work and sill. Coat the window seat, if you have one, using a paint roller. Paint a second coat as needed.
Create a clean, contemporary look by adding dark or bright accent cushions. If you have a window seat, try basic black or dress up your window with stylish leather upholstery. Add two or more pillows to complete the window seat look. Avoid flowery patterns or frilly prints, and opt for solids or suede textures.
Add to your contemporary look with a sleek, modern curtain rod. Choose a polished silver or jet black rod in a simple style that lacks fancy embellishments.
Hang curtains that you can easily move or pull back to expose the natural light provided by the bay window. Decorate in a contemporary style by choosing bright solids or even geometric patterns of drapery fabric. For an ultra contemporary look, hang straight or flat panels of fabric on either side of the curtain rod.
Hang shades across the window area. Choose a simple, neutral pull-down or Roman blind in a basic color for a contemporary feel.
