Red and green aren’t usually considered good to mix in the interior décor but still these are colors of Christmas and they also look cool in all the other seasons, especially in summer when we want bold shades. Red and green combo is great for various interiors: modern, retro, mid-century modern, Moroccan and many others, and you may use them anywhere, from an entryway to a bedroom. There are certain tricks you could use mix them well.
First, you need to choose the best green and red shades that go very well together to decide whether you are going to use them as primary and secondary colors or just as accents. Brighter colors are best used in accents while primary colors are best kept mute. For example, you can make calm sage green walls and accentuate them with red ottomans and chairs.

Here the dark green and bright red look great together. White space between patterns balances it out and lightens up the room, which would be very dark if it was painted green entirely.

Equally bright red and green accents work great even on duller green background thanks to monochromatic combination of colors.

Here are a lot of neutral colors that don’t clash, while red and green make the space look livelier.

A living room furniture set doesn’t have to be a uniform color. A colorful area rug can bring different color pieces together.

Small doses of color punctuate the room, most notably the scarlet lacquer side table and velvet upholstery of the side chairs.
Making one of the shades brighter is a great solution for continuous space. Equally bright red and green accents work great even on duller green background thanks to monochromatic combination of colors.
Neutrals with bright inclusions and accents work great in any style. Sometimes one color can be a bit more dominant in a still neutral scheme to create dimension. Make a neutral-colored room with bold red and green touches: furniture, rugs, artworks and accessories.
