Here is a demo in playground:
It demonstrates how to create a shining sun surface with particle system. It is expected to display like below:
But actully it appears with red color globally:
Anything incorrect about that?
It displays correctly in the playground! Where does it not display correctly?

Oh, is it right? I saw it outght to be the same as the overview pictuture before entering the playground.
So, I considered if there is anytying wrong.
Thanks.
It displays correctly for me too, like in the first picture you posted, like on the PG link before you click it - on my MacBook and iPhone at least, on Chrome, FireFox, and Safari. 
Yes, I would check what goes wrong.
I Checked the trouble is that the texture pictures can not be pulled from:

Maybe here in China the url is masked by national security firewall.
Would you help me download it and send it to zhengzuowu@outlook.com？
Thanks a lots for your goodness.
Heya, can you right-click below and “save image as” to download it from the forum? I just copied and pasted the image onto this post. It’s hard to see because it’s a white image on white forum background, but should be below to right-click on it below
