Why not overseed with what you want, provided it's a cool season type?

Is this a new house, meaning could this be a contractor's grade sod?

It looks like a blend of fescues, tall and fine, but don't take my word. Maybe someone can identify the close-up pic. If it was me, I would look for another blend of mostly TTTF but with some KBG and maybe some rye in order to diversify (for your shade, grade, etc.). Then, then allow the best-suited grasses to take over. That's what most blends do and that requires a couple of years to grow-in.

 

It could be a northern mix - Fescue, perennial rye and KBG.

While different grass types have different genetic colour, over time an over seed will blend in with the existing grass and you won't be able to tell the difference. New grass comes in lighter and darkens as it matures.

You are never going to completely match the colour unless you kill what you have and start over. Not all perennial ryegrass varieties, for example, have the same colour. The same is true of KBG and TTTF.

Well, I just want it to match and be dark green, but if all cool northern grasses eventually darken into the same shade that's fine then.

Yes it's a new house and the contractor laid the sod, why? Thank you

 

Most aid mixes are tttf here in NJ. If you can get a shade mix it will have fine and prg mixed. Not that common though. Premium sod usually has kbg mixed in. I would just overseed with a 3 or 4 way blend of tttf, it does pretty good with shade as long as some sun creeps thru

 

Sounds like a blend of KBG and TTTF would be best - it's hard to tell what all these mixes actually have in them though. Any suggestions?
