For the 1st Image :

In my perspective, there is no such thing as a gendered color. Pink can appeal to both boys and girls. Any color can be appreciated by anyone, regardless of gender. Therefore, it is absolutely valid for boys to like the color pink.

Here's a simple version incase your teachers might be suspicious of your work hehe

Color, in my opinion, does not have a gender. Pink is a color for any gender, anyone who says pink is only for girls is ridiculous and childish.
