As discussed, swapping bright whites for warm beiges adds a hint of the textures and tones found in fall decor. In the same vein, one might choose muted earth tones over sugary pastels for summer to achieve a similar effect. Consider elevating traditional spring and summer color palettes by replacing lilac, mint and sunflower yellow with mauve, sage green and a mustard yellow. Allow navy or dove gray to replace baby blues and tan to replace pink. Using prints with small accents of these darker, deeper and more saturated colors will create a more effective, gradual transition than will replacing blocks of color.
