Merits of colored primer

[Deleted]

Sorry, this is going to come off as a mildly vague question mostly because of lack of pics but I'm looking for feedback on use of primer.

I have to date only used black primer on my minis barring a single white primed gaunt. I've liked the results, but my color scheme consists of red talons, black carapace plates, and leather/khaki flesh-tones. I was wondering though if anyone with similar flesh tones had tried armypainter or some other brands colored primers because I was considering ordering their darker brown primer to speed up some detailing work(I use a dark sepia wash, but figured the flesh tones MIGHT turn out better with brown primer). 

Other fleshtones input is welcome(with the appropriate matching color primer of course). 

So how would you rate your experience with colored primer(or why do you choose not to use it other than old habits dying hard)?

I've used plain old Krylon or Montana Gold spray paint (after priming with a real primer) and it's worked out decently. The Montana Gold would sometimes resist my washes in annoying ways, but it was manageable. Strictly speaking, the primer's just there to be a better surface for the paint to stick to, so as long as the colored primers are actual primers, I'd say go for it.

I did my whole Skaven-counts-as-Tyranids army using Army Painter Leather Brown undercoat; I then used the washes range, mostly Devlan Mud for fur, skin, timber etc, mixing with other washes to get variation. 20 Termagants/Clan Rats would be done in an evening.

My current project, a bright red pirate army based on Dark Eldar has all been done with AP's Pure Red, which explodes off the models beautifully.

I am not good at painting. I don't enjoy it. My aim is to get to tabletop standard as quickly as possible.
For this, coloured primer is awesome, removing a big chunk of the basecoat painting.

I tried AP's dip, and didn't like the result: too gloopy, loss of texture, and the gloss finish then needs to be matt varnished. Getting the hang of sloshing washes and glazes around is much easier, I find.

TL:DR, if you are looking for tabletop quality, and your army has a majority colour, coloured primer is a huge time saver.

I switched to using Army Painter primer last year, initially I just wanted a quick way of painting some ultramarines for my son to use, but I was pretty happy with the results, so I decided to give it a go for my guants. Off the top of my head I think the color I use for my Nids is called Dragon Red. Once again I was pretty happy with the results and the amount of time it saved me (I am a slow painter) so I tried it out on some bigger bugs and have been using it exclusively ever since. I'm not a fan of the look of dipped models, so I use it with GW washes and layers to get the look I want.

Recently purchased Army Painter color primer Goblin Green (may not be called that, but it's a 1:1 copy). Haven't had time to try it out as of yet (waiting for new models as well), but I'm hoping for a more swift experience. I hear good things about them, though (army painter's primers).

Don't use it without a brush basecoat after. What I do is I spray my minis with white (even if it doesn't cover 100% it's not important) then give some sprays of Army Painter to give the model a rough basecoat. I then complete it with a brush.

The reason why I spray with white before is because the color sprays seem to be covering less than the 'base' ones (white or black). Give it a try, it really saves time on a really boring step in painting that is basecoating
