Emissive Particle Color?

So i just upgraded to 4.6.1, and the new particle UI doesn’t allow mo to raise my particle color past 1.
I looked at my other sprites from before the upgrade and their colors are still over 1, and when i try to change the old ones it forces it to 1.

How do I raise it higher?

That’s a known issue. It’s fixed in the 4.7.0 preview. That’s what I did for my project.
