L and R channel/Red and White in system chain


I'm going crazy over this and I feel totally confused + angry. Anyone up to solving this puzzle?:

Turntable junction box: color coded white and red;
Phono preamp: engraved R(ight)(white terminal) and L(eft) (black terminal);
Rumble filter: no color coding; just L and R input and output terminals, both white;
Main integrated amp: no R or L but only Red and White inputs (CD player that's partner to the amp says Red is Right and White is Left channel)

I am so confused as to how to connect the cables it drives me nuts. I thought Red is always Right channel; but my phono preamp has Black marked as Left and White as Right.

The rumble filter has no color at all and only says R and L, but if my main amp Red/Right and White/Left that different from the phono preamp. The sound seems ok in either combo but it angers me that I have to play a guessing game with high end stereo equipment. Please advise.

Take a red marker or touch up paint and mark all the right channels as red. Life is too short.

Actusreus,
My comments were tongue in cheek i.e. red and white vs. black and white. I did not mean to take them literally.

When you have to explain a joke, it's a bad joke.

Sorry.
Elizabeth, your explanation seems to make sense and takes care of the problem! Thank you.

Bill, I did miss the joke but I'm fully enjoying it now! And I have learned that things are not always black & white...

I think we can lay this post to rest now.
