is the "White" House a subliminal metaphor for white supremacy? don't answer until you know what the words subliminal and metaphor means.?

No. Metaphors are not subliminal. They do not exist unless they are written, spoken or read.

It you're looking for a way to describe a visual suggestion, maybe you need to learn words like "symbol" or "leit-motif."

The White House being white does not mean what you think it means. They didn't have Sherwin-Williams paint stores back in the day. 

Well if we paint it pink can be call it the "Pink" House?  Gosh, you guys are getting ridiculous.  People are black and people are white but mostly they are many shades of brown.

Personally, being white I would never have thought of white supremacy, not ever.  If it had been black, I would never have thought of black supremacy. Or "Red Door" I would never have thought of Indian Door or Indian supremacy.   

My how your mind works or "What a wicked web we weave, when we practice to deceive."

it can mean whatever you want it to mean...seeing as the "subliminal" stimulus could be your own bigotry and bias...which clearly exist below your conscious level....

meanwhile, ever notice how so many of the biggest "voices for racial justice" are white?  any "subliminal metaphors" there?

No.  The color of the house is white.  Period. 

Nah.

Actually, they wanted to call the  "Presidential Palace" something else, "The White House" was adopted out of simplicity.

That way it wasn't tainted by the scent of Monarchy.

You wouldn't be 'suggesting' that we perform a fiery act of 'social justice' on the 'White' House would you? That would be a criminal offense. You mean that it should be renamed to something more like the 'Rainbow' House, right?

Not any more than "white" bread is a metaphor for white supremacy. And stop acting like trump by implying that people don't know those words. Most of us do know words that have more than 2 syllables.

I think it has more to do with the colour it is painted.
