By flooring samples, do you mean LVP? Tile? It would help if you posted pictures of adjoining spaces, especially if your kitchen is open to other areas. I personally like natural hardwood, which would let you select a stain that works best. Not everyone likes or wants hardwood, so please let us know what you're considering.

Are you getting new cabinets? If so, have you chosen a color or stain, or are you waiting to pick your floors first?

Here is how to post a Design Dilemma to get the best results. You need to show the whole space—all four sides of an entire space—even if it’s about one specific Dilemma.

State right at the beginning what the room will be used for and who will use it. State the non-negotiables at the beginning, what has to be kept. Give some idea of the budget.

Keep in mind that you're inviting some design pros and people with a design eye into your home via photos. If they walked into your actual space, they would take in all of it: all four sides, doorways, floors, windows, ceiling, built-in fixtures, lighting, trim--the "givens"--then the features that can be changed--furnishings, paint, art, rugs, decor items, etc. It's all one first impression. Same thing with photos. That's why it's important to provide well lit photos of the entire space, taken from all sides of a room regardless of the size of your problem.

Give us a clue as to what type of flooring material you’re looking for. Your description of colors could be anything…tile, wood, LVP, cork…?

Like @chicagoans, I prefer natural wood. Wood can be stained any shade you want. You can combine stain colors, to get the desired shade. If you have wood elswhere, extend it into the kitchen, and have it stained to match.

What is the flooring in the rest of the house ? IMO that is usually the best choice but really no idea about anything you are doing . No context no help Post pics here in jpeg format in a comment DO NOT start another post.Unfinished wood can be finished to match what you have.

Yes, please post some pics of the kitchen and adjacent flooring.

As stated, no clue what you currently have,.

If you have hardwood? You can add to it and refinish. If you want to replace ALL the flooring? You need to show the materials you are using and add pics of adjacent spaces.

You are giving us nothing in formation to help you.
