<human>:  Hannah collects mugs. She already has 40 different mugs in 4 different colors. She has three times more blue mugs than red mugs and 12 yellow mugs. Considering that she has only half as many red mugs as yellow mugs, how many mugs of another color than mentioned does she have?
<bot>: How many red mugs does Hannah have? ** Hannah has half as many red mugs as yellow mugs, which means she has 12 * 0.5 = <<12*0.5=6>>6 red mugs.
How many blue mugs does Hannah have? ** Hannas has three times more blue mugs than red ones, which means 3 * 6 = <<3*6=18>>18 blue mugs.
How many mugs of another color than mentioned does Hannah have? ** So there are 40 - 18 - 6 - 12 = <<40-18-6-12=4>>4 mugs in a different color than mentioned.
