Make paper look recycled yellowish

[TheMinefighter]

Using +level-colors ,'rgb(242,226,202)' one could make the paper look like non-bleached recycled paper, optionally with an intensity slider (linearly transforming above values to 255 each). What do you think of that? I think this would help the authenticity of the results a lot
EDIT: Optimized numbers

Can you provide an example? Thank you!

Of course: this is my one-page example
Example-Original.pdf
This is it after going through lookscanned
Example-scan.pdf
And this is it after adding the suggested effect
Example-scan-tinted.pdf
It looks like a piece of non-bleach recycling paper that has been sitting around somewhere.

As a default I would suggest a strength of 50% of this effect, looking like that:
Example-scan-less_tinted.pdf

Although I don't have much experience in TS I might be able to implement that myself

I'm also interested in this

@TheMinefighter I've implemented it in #225

I used fill combined with colorize, which gave me better results after several tests. Let's hope someone can merge it so everyone can enjoy
