@Tricotou, the better option than color1, color2, colorDead is color gradients. This PG is using a transparent png with standard blend mode so your particles are always a solid color no matter what your background is. Using color gradients allows you to not only control the color over the lifetime by setting the start color and the end color, but you can change the color at any point in the lifetime of the particle. You can also set the final color to be at any point in the lifetime such that you could say I want the particles to start red, but blend to blue in the first half of their lifetime and stay blue after that. I hope this helps, but if this isn’t what you are looking for, please feel free to ping back with more questions.
