Oh, I see.
The color red is a warm color, also one color that mostly represents friendship, and a lot of strong feelings compared to the other colors. And that's why, this time I retry it, I only was picking the color red.
For now, they are only colors, but the addition of some objects or ideas in the bridges giving some hints of what is the most selected path would fit very well.
But I think you already thought of that.
