<human>:  Amy had two eyeshadow palettes with four colors each and three makeup sets that came with six eyeshadow colors each. Her sister steals one of the palettes. Amy uses up half of the colors from one makeup set. How many eyeshadow colors does she have left?
<bot>: How many eyeshadow colors did Amy have to start? ** Amy had 2 * 4 + 3 * 6 = 8 + 18 = <<2*4+3*6=26>>26 eyeshadow colors to start.
How many eyeshadow colors does Amy have left? ** Her sister stole one palette of 4 colors, leaving Amy with 26 - 4 = <<26-4=22>>22 colors.
How many colors are in half of the makeup set? ** Half the colors from one makeup set are 6 / 2 = <<6/2=3>>3 colors.
How many eyeshadow colors does Amy have left? ** Thus, Amy has 22 - 3 = <<22-3=19>>19 eyeshadow colors left.
