I personally like bright colors....I choose bright bold feature fabrics and then put blenders/tone on tones with them or throw in some black or other really dark colors to make the brights pop
I love to go through the rows of fabric and stack boldts of them all up together on a table and then stand back and look at them...some come out then, and I may go find something else to replace it...I will keep doing this until I am happy with the combination.
I have been collecting eye hurting bright, bright pinks and oranges for a while, added a piece of the brightest light neon green to them a while back....I guess I am not afraid of color 8)
My struggle is with hues/tones...muted fabrics....
