my headboard is a dark brown shade and also what color sheets?
since blue and red are very dominant colors, i would stick with a white sheer curtain and white sheets. if white sheets is too boring, get something white with a blue or red accent that matches the walls. Do NOT do black, because black and brown definitely do not match, and black curtains will not let any sunlight in making your room seem very dark and small.
red or blue curtins and bedding, or a print that has both in it
Dark blue ,navy blue,or maybe even green.
