I personally haven't had that issue, because I like scrappy, so when someone specifies a certain color, I use all shades across that specific color spectrum. I.e. if they want green, they get sage green, forest green, frog green, dusty green, kelly green, yellowish green, blueish green, etc.
When my SIL got married, a relative asked her what colors she liked, she was going to make a Lone Star quilt. She replied "earth tones". Well, that is rather vague and can mean many different colors to different people. SIL meant blues, greens, and soft browns. What she got was greens, oranges, yellows, browns, and fuchsia. That poor quilt didn't see the light of day for 20 years.
