What is the basic consensus here when mixing greys for castle building? I don't seem to have enough old grey bricks to build my own castle, but I may be able to with my new bley bricks from current castle and lotr sets. Would it look too bad, or do you think it would create a level of realism since not every stone is the exact same color in real life?

I don't have a problem with it. I find it adds some nuance to have some variation, though I do feel it necessary to make sure it's fairly evenly distributed.

I think variation on colours looks good.

I think as long as you are using other techniques to add variety to your architecture then heck yeah, it will only add to the realism of the build. A castle wall built simply from standard bricks doesn't look great in any color. I do have to say, I've felt great peace since the day I finally weeded out my last dark grey and light grey pieces!

I would want to mix greys. The difference in the greys will make it more realistic looking.

I really like the look of mixed greys. Especially when other detail is added.

Light greys are fine to mix, dark greys looks really bad mixed. It does add variety, but the two colors do not go well together. One is more of a brownish grey and the other is more of a bluish grey. It really does not work well. Worst decision by Lego since fleshies IMO.

I like mixing grays for stonework, it makes for an authentic feel, as others said above. Contrary to some opinions I've read on this site, I think the older, slightly yellowish (dark) gray was better for rocks, as rocks in real life are more of a dusty or tan gray. The current more bluish gray seems more metallic. Anyway, the more authentic look from mixing grays is the one silver lining about the switch to bley, IMO.

Worst decision by Lego since fleshies IMO.

Go for it! The proportions of each grey doesn't matter. I've seen mocs look great containing anywhere from equitable amounts of each color, to just splashes of a secondary color. Good luck and look forward to seeing what you come up with.

It is all good until the sorting begins... then I regret these type of decisions.

For castles it can look great or terrible, I think it depends on the architecture / style, but personally I think mixing generally looks better than not.

If it's what you've got to work with, go for it.

+1 to mixing greys. It gives a lot of "texture" to otherwise boring walls

I think miwed definedly look better. As others have stated it can also look like crap though. For me it looks great with mixed colors in very simple architecture, where as more elaborately decorated architecture tends to look better in one color, maybe with a couple of differently colored bricks, but few and far apart. Otherwise you simply end of having to much going on, and it will just look bad.
