Grow Poplar Trees with Specific Leaf Colors

I think it would be better for builders if there was a way to grow the Poplar trees with specific leaf colors instead only having the option of it being random. My 2 suggestions would be either:

1. Give each color Poplar tree its own sapling (Red Poplar Sapling, Orange Poplar Sapling, Yellow Poplar Sapling)

2. Have growing the sapling on a specific block always generate a specific leaf color - ex. growing the sapling on mud always makes a tree with red leaves, growing on coarse dirt makes orange leaves, and growing on rooted dirt always makes yellow leaves
