Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In an art class, students are painting still life scenes using three primary colors: red, yellow, and blue. Lucy paints a picture using only red and yellow, while Michael uses only blue and yellow. During a break, the teacher accidentally mixes up the paint palettes. When the students return, what colors will Lucy and Michael think are on their palettes, and how will they react when they see the mixed-up colors?
Provide a brief response.

Lucy, having painted with red and yellow, would expect to see those colors on her palette. When she sees the mixed-up palette, which has blue and yellow from Michael's painting, she'd likely be surprised to find blue instead of red. Since red and yellow are used to create oranges and warm tones, the presence of blue may confuse her because blue is a cool color that can't mix with yellow to create the red tones she was using.

Michael, having used blue and yellow, would anticipate these colors on his palette. Upon returning, if he sees Lucy's palette that has red and yellow, he could be puzzled by the absence of blue, which is essential for creating various shades of green and cool tones when mixed with yellow.

Both students might initially think there was a mistake or that the palettes were switched. Once the teacher clarifies the accidental mix-up, they would understand the confusion and then either clean their palettes to get the correct colors or swap back to their original ones.
