What is one reason blue copy paper is effective for homework assignments?

Blue copy paper is considered effective for homework assignments primarily because it enhances students' visual engagement and motivation. Research has shown that certain colors can influence a reader’s willingness to engage with text. Blue, in particular, is often associated with calmness and can make the reading experience feel less daunting, leading to increased willingness to tackle reading assignments.

This increase in willingness to read can stem from the psychological effects of color on mood and focus. When students face homework on blue paper, it may help create a more inviting and less sterile environment, encouraging them to approach their assignments with greater enthusiasm and attentiveness.

While the other options mention valid points, such as environmental friendliness and cost, they do not directly connect to the specific effectiveness of blue copy paper in enhancing reading engagement and willingness, which is crucial for student learning and performance.
