# Objective This change substantially increased performance when drawing thousands of colored sprites. ## Solution The same color is used for each vertex in the quad sprites are drawn too, but the color is converted to a linear color each time. This computation only needs to be done once. The `as_linear_rgba_f32()` call was showing up in profiling the `basic` example in my [particle system library](https://github.com/abnormalbrain/bevy_particle_systems) as a hot path. This change added about 50 fps to the example, from about 150fps to about 200 fps, when rendering around 10k colored sprites. Tracy Results: "This trace" is with the change.
