Colors do not exist out there

This should make you question whether reality is real.

You mean whether or not how one experiences reality is ultimately real?

Reality is real by definition. 

Like for example, questioning why theists constantly cherry pick real life scenarios and then conflate them with their myths and superstitions?

Wouldn't you agree that the reflected wavelengths that we perceive as color are real?

I think it's more likely that wavelengths are just a visual representation of mathematical disparities 

So you have great difficulty in recognising reality? Is that why you believe in gods?

Consider a red ball.   It is perceived as red and spherical.  if its redness is not 'out there', is it being round aslo not 'out there'?

Yes

In your opinion, does anything exist out there apart from mathematical disparities?

It's hilarious how Theists tell us how reality is not real but they're magical invisible friends are real.

I do question whether reality is real, but in the end it is the only reality that I can perceive and so I'm incl8ned to accept it at face value as a convenience.
