I changed the color of the painting

I used to work in a gallery and one day a painting was delivered in the wrong color. My boss was angry as it should have been red and black but it was red and yellow instead. The painting was so big and canvassy that we weren’t able to send it back, so I went out and bought some black paint and actually painted over all of the yellow on the painting. None of my coworkers noticed and I ended up getting a promotion. It was mad.
