If you are shooting digital, just shoot in Colour RGB and convert it in Photoshop or similar software. Do not shoot in B&W as you will lose information.

I think the original poster was referring to numerical filters for digital photos.

Regarding your question, the spectral sensitivity curves of the human eye and panchromatic b/w film are quite different. The human eye has its maximum sensitivity in the green range, whereas b/w material is more sensitive to blue. Green or yellow filters can correct for this to some extent.

DSLR - it won't help you to achieve film-like BW even with filter.

You need to use PS to tweak it - try channel mixer in PS it yeild better BW result.

Filtering is largely a matter of taste, so you have to find out what you like. I think orange or even red filters used to be popular for landscapes as they can result in quite dramatic sky. Apart from how different colours are rendered, going towards the red end of the spectrum also reduces the effects of atmospheric scattering (haze). Then again, in some landscape photos one may want to emphasize the haze and even use a blue filter. There is no clear cut "right" and "wrong".
