Winter and spring. Summer and fall.
In the winter and spring time it is best to wear blush, to make a rosy cheeked look for the cold days in winter and a preppy pink color for spring. And for fall and summer you should wear bronzer. Bronzer creates a warm, sun kissed glow for your skin in the summer and continues through the fall; bronzer colors are usually good matches with fall's natural colors. Blush in winter then spring, right after each other, and bronzer in the summer and fall, consecutive also. Now if you don't want to do this everyday for these seasons, sure that's fine, do whatever!
