Hi,  
I have a quick question:  
Im running an expression where  
if({some tag} ||{some other tag}, color(0,256,00), color(265,0,0))  
How to set one of those colors expressions to blink?  
Thanks

The easiest way to do this is to add a custom property to your component, then use an expression to toggle the state, and then control the blinking using the [Style Customizer](https://docs.inductiveautomation.com/display/DOC79/Component+Customizers#ComponentCustomizers-StyleCustomizer).
