This really caught my eye-bright blue and purple succulents. Turns out these have been lightly spray painted. I also read that you can put food coloring in water and water the plants to change color which I have to try:
“Add 1 tsp. of liquid food coloring to 1 cup of water. Drizzle the colored water onto the soil surrounding the base of a plant. Wait 24 hours for the water to absorb. Apply another identical dose if the color change was not sufficient.”
