I spent years searching for orange fabrics when it was almost impossible to find them. Orange, not peach, not coral. Finally I collected enough to make a quilt I named "I Like Orange". The background is tone-on-tone black and each block has a dresden plate with different orange fabrics -- some have accents of other colors, some are Halloween fabrics. I decided a queen-size quilt would be too much so still have blocks left for another project but I'm very happy with it. Orange is my favorite color and now, of course, you can buy tons of it anywhere.
If you're nervous about it, just lay whatever orange fabrics you have across your bed and let them stay there for a while. Every now and then take a look at your bed and see how it makes you feel. My opinion - go for it!
