What is the original granite?

If funds are tight, wait until you have money to do all counter tops at the same time. Granite colors vary so you want to get what you need,all at the same time. Quartz is also nice. Recess lighting is good. Lights under cabinets is a great way to add light.

That will never look good i agree wait until you can get all new granite or switch to laminate and replace it all now.

Try not to go laminate, I did years ago and was never happy with it, now I'm getting new Quartz countertops.
