Meaning of blue

Our class had a color to choose to collect things and I wanted purple but the color came out to be blue. We had to collect whatever, but it just had to be blue. Since I was late like always I brought a blue paperclip and i colored a blue piece of paper. I think this is so cool to do this because everyone didn't just bring the same thing everyone brought something different and i thought it was pretty amazing to see all the different things everyone had or found. I thought the most cool part was taking the picture which i will upload separate.
