Subjects You're Having A Hard Time Researching

[Waterberry]

Are there any subjects you're having difficulty researching, online or otherwise?

There's many subjects I wanted to know about, but the only one I can think of off the top of my head right now is what shades black and white film converts different colors to. What shade would cyan be, for example?

What is the idea of the topic ?

isn't there an equation for RGB colors to B&W?

Are you talking about for example, in a image editing program, you can instantly convert an image to grayscale by clicking on a menu button, like, for instance, "Image > Mode > Grayscale" in Photoshop? I'm not sure if that would accurately represent black and white film.
