How do I assign sprite color from the event correctly?

Hello all!

I would be very grateful if you could help me to solve the next problem.

I have a sprite in my project which I would like to change color randomly on the start of layout. Default sprite color is white. When I am changing its color from the Properties panel it works great but when I am doing it from the event sheet using Set color action I get a strange result.

I don't know what this could be about. Any thought?

Thank you very much for the help in advance!

Here is c3p if needed

Remove the Ex from rgbEx

Use rgba instead.

Thank you guys! Went to read what it is...

Can't even tell you why my solution works =P

RGBex max value is 100.
