Currently, as of 12/04/2020, directly setting the color3 property of a particle in studio does not work as expected. If you set the color of a particle that has colorsequence data associated with it, any changes you make are not saved after closing the color widget, as the colorsequence overrides it instead of being cleared.
Steps to reproduce:
Insert a particle emitter into a part
Attempt to change the color of the particle by clicking on the color square button. Select a color from the color widget dialogue that comes up, then click “OK”.
Notice how the particle has not actually changed colors.
Now, click on the “…” button to the right in the color property section. Change the colors of the color sequence data in the dialogue widget that comes up.
Note that it looks more like the Color3 input in the properties widget isn’t actually updating the instance. The widget updates when you change the Color3, but if you deselect and then reselect the particle emitter, the properties widget reverts to what it was previously. Setting a colorsequence first is not required.
Thanks for the report! We have identified the offending flag, but due to ongoing platform issues we will be unable to disable it until Monday. It is possible to work around this until then by using the full ColorSequence editor (“…” button on the property) or by setting the property from the command bar
