- Project A uses three colors with equal numbers of beads (red, black, and green) totaling $$825$$ beads.
   - The number of beads for each color is:
     $$
     \frac{825}{3} = 275.
     $$
   - This project requires $$275$$ green beads.

2. **Project B Analysis:**

- Project B uses four colors with equal numbers of beads (black, blue, green, and yellow) totaling $$1020$$ beads.
   - The number of beads for each color is:
     $$
     \frac{1020}{4} = 255.
     $$
   - This project requires $$255$$ green beads.
