I completely agree with Dave_P and Charles Oates that the Vallejo Model Color range is very good indeed for brush application, if one is looking for water based acrylics. The range tends to be a bit skewed towards the needs of the armour and generally 20th century military modelling community, with umpteen shades of olive drab available, but one still finds just about everything that one needs for ship modelling purposes, too.
The range also includes some quite good metallic paints; not least their brass and copper paints are very good.
Vallejo paints have the further advantage of being widely distributed, and are often available in shops catering to the plastic modellers, and of course also in many, many online modelling shops.
Please note, though, that there are two main model paint ranges from Vallejo: the Model Color, primarily intended for brush application, and Model Air, with finer ground pigments and more heavilly diluted to suit airbrush painting. Although with appropriate measures either can be used with both application methods, I have found that it pays off to respect the division, which means that one needs to make sure to get the right one when buying (at a quick glance bottles and labels for the two ranges look quite similar).
As concerns mixing one's own colours from any range of paints, I always do this by weight rather than volume; that way, it is quite simple to replicate a certain mix at any time with sufficient precision to match the previous batch well enough. With a set of precision scales like for example these **LINK** paint can be weighed to the nearest 0.1 or even 0.01 grams. In my experience, for the quantities of paint involved in modelling, the 0.1 grams degree of precision is ususally more than good enough.
