Particle emittor incorrect colour

[jrutgeer]

Environment

• OS Version: Ubuntu 22.04
• Garden, source built
• Ogre2

Description

Run particle emittor demo world:

$ gz sim particle_emitter.sdf

The fog looks correct but the 'bright red´ particles are black. There are red 'flashes' that lead me to assume that the particle is initially created in red, but on a successive render call is rendered black.

gazebosim/gz-rendering#903 should fix the color issue for this demo. Ticketed a separate issue to track the root cause of this color problem in gazebosim/gz-rendering#902
