Has your TFC Tracks and TFC Astrotrain started yellowing?

[primatives]

Anyone who has TFC Tracks and TFC Astrotrain, I was wondering is the white plastic bone white or is it slgithly yellowy cream??? I have them both and Ive noticed that my tracks looks like its in ver y early stage of yellowing I could be wrong but like I said the white plastics has a tinge of cream,yellow. not sure but if anyone else can have a look at theirs and let me know that would be great. My astrotrain still looks pretty white but again kind of looks like it has a tinge of yellow cream. My toys arent in direcct sunlight but my room does have fluroesnt lights. thanks

I too have noticed it a little with my classics/universe grimlock and starscream.
The parts on starscreams back seems to be a little yellower than the wings.

I have a Tracks reissue I got loose but not sure what version, his head and wings are whiter than the other white platic on him.

I wish my Red Alert reissue would yellow a little it looks so white....
