An issue I’ve experienced for many months while working with Particle Emitters is if you select the Color property and copy it to your clipboard using CTRL + C and then go to another particle emitter and click on the Color property and press CTRL + V it will create a ParticleEmitter in Workspace rather than pasting your value.
This bug has become extremely annoying and inconvenient while trying to work with Particle Emitters in studio.
This is because ParticleEmitters don’t allow you to enter anything into them (if you manually typed out the value with the field selected, nothing would happen). This is both unfortunate because it misleadingly seems as if it allows editing due to UX, and because you can’t paste/edit the color directly.
This is intentional, so you would need to make a feature request.
