Hello Marqs,
Thank you for the reply!
Unfortunately I have only one display that has composite video input. (Sony Trinitrion)
With an unmodified 3CHIP PAL SNES it works fine. I can try PAL mode with PS2, too, but I think the TV is okay. Just to be 100% sure, I will check it also with a pal ps2.
I've just tried my 1CHIP PAL SNES with borti's earlier superCIC + uIGR board + DFO, without the dejitter feature, and surprisingly there was no color via composite in PAL mode, but I guess that is a completely different issue.
I have a very limited amount of games, I'm not sure if some of these have interlaced mode, but probably no.
PAL Super Mario World, Super Mario All-Stars
NTSC-J - Yoshi's Island, Donkey Kong country 1, Kirby All stars, some game with a cat, and one dragonballZ game, I dont know which one
NES/SNES 240p dejitter mod
Re: NES/SNES 240p dejitter mod
I can only speculate that the 21.28137MHz and 17.734475MHz clocks generated by DFO are not synchronous (i.e. with exact 6/5 ratio) as in genuine PAL 3-CHIP with S-CLK PLL. None of the listed games use interlace modes as far as I know but it's unlikely to make a difference.
Re: NES/SNES 240p dejitter mod
I find this issue strange, if the clock sync would be the problem, I guess others also would have reported this. Or maybe I am the only one who tested composite out on this pcb revision 
I also use rgb in general, just wanted to make sure that everything works as expected.
I created an issue on Borti’s github page, maybe he will have some idea what could have went wrong/how to fix it.

I was thinking about reflowing the cdce913, but for ntsc mode clock the same output pin is used on it so I do not know how much sense would it make.
Other idea is to replace the cpld, it is from aliexpress, so who knows what happened to it in the past. Although I kind of doubt it would make any difference. (Cdce913 purchased as new from a reliable source)

Re: NES/SNES 240p dejitter mod
I replaced the CPLD just in case, although it is from the same batch as the first one. Unfortunately the discoloration is still present in PAL mode.
I am using a different crystal (9C-27.000MAAJ-T) compared to the one in the BOM, although it seems to me it is an equivalent part, but maybe I am missing something(the one in the BOM is obsolete)
I am thinking about trying out an Atmel CPLD, but I do not have programmer for that. It does not make any sense to me why it is not working properly in PAL mode. CDCE913 is from Farnell, PIC MCUs and the Altera CPLD is from aliexpress, but even if the CPLD is dodgy, I find it very strange, that only PAL composite video is affected.(+ I guess S-video, but I don't have a cable for that)
