(I actually HATE camo because it does its job too well and obfuscates the lines on the Battlemechs)
Trick is to do camo "not so effectively". I've seen really accurate depiction of digital camo on BT minis, and yes, the result is a blur. There are tricks though ...
1) Give the whole mini a base coat in one colour - green or brown, most likely
2) Use contrast patches or stripes in another colour - eg. brown or green, or dark green, or light brown. Do it bigger than "real".
3) Use a wash to bring up the panel lines
4) Colour bits in metallic (eg. drybrushed over black) - heat sink grilles, accordion joints, gun barrels, other joints, weapon feeds.
5) Use trim colours to brighten the mini and bring attention back
The result isn't "realistic" - I tend to use the term "enhanced realism". These 12th Falcon Regulars are in "Auscam" camo:
The broad brush, red missile tips, and a little jade trim help draw attention. Similarly, these Hell's Horses Delta Galaxy are "red desert MERDC", but with enough details to catch the eye:
So yes, aim for 'flashy' camo - it's not realistic, but it looks real-ish, and highlights the mini. IMHO, of course.
