Brown vs brown vs brown?

[ChrisXY]

Stumbled across those piece

I guess left is reddish brown, right is old brown. But this one in the middle? According to bricklink there for this jumper no groove only the two browns were used. So middle one is discoloured?

Looks like faded reddish brown to me @ChrisXY.

Thought the fading won´t appear on the "newish" colours?

@ChrisXY White yellows, brown fades, etc. It's just a fact of life, but it's not always guaranteed to happen for every part. It's a variety of factors that cause this: UV radiation, age, slight chemical changes / fluctuations when it was made, temperature of the area where it is currently, physical stress on the part, humidity, and so on. I had a MOC from 2016 where some brown parts faded, and some stayed vibrant. (Then I took it apart this year and a lot of it shattered - no matter what the fade factor was...)
