Render view

I often see all the colors when I work. Even If I dont have the Render view on.

but now or then when I open an scene some colors are white. Others are correct. When exporting they look corrects but some how it seems like there are some function I missed. Cant find out what it is.

I understand what you mean:
are you enable the “Light Table” function?
shortcut is “Shift+L” to on/off light table.

right?

Could you send a screenshot?
or send to my e-mail:

I will check is this is the reason. Thanks.
