I had some black mold on side of home and decided to purchase a cedar safe wash on Amazon.
Sprayed cleaner on and starting lightly pressuring washing.
I removed some type of sealer of stain that had a white coloring to it.
The product that was coming of the home was glue type of sealer.
I sprayed a sealer protective sealer on afterwards and have a big issue now

Any thoughts on what i can use know to get coloring back? The natural look isn't a option
Thanks

Not exactly sure what your issue is or what you're saying but that looks like typical cedar after pressure washing. I'd finish the whole thing then decide if you want to apply any type of sealer/stain. The color will naturally lighten over time to what the top of that side of the house looked like if left natural.

Thompson water seal that has a tint or something like that. I didnt exactly do siding with it, but I did the sides of my kids play set and the effect was to add a hue to the natural cedar when sanded (or pressure washed). Do test samples first.

Likely never going to be able to make it match. As others said, you’re likely stuck doing the whole thing.

If you’re removing “pieces” of the old stain/sealer- there’s definitely a problem with that application.

So, you’re probably looking at at least doing the whole side of the house.

As far as what is there- I’m thinking “pickle stain”. IIRC Minwax had a stain that was called “pickle” or “white pickle”. This is just a stain- it would still require a sealer over it. And an oil-based sealer would be the preferred sealer, due to its penetrating properties.

Looks like it was painted or stained white. I would take some pictures down to a good paint store like Sherwin Williams or Benjamin Moore. I'm sure they can find something close but you will most likely have to do at least that entire side of the house if you want it to match.

Where are you at in Medford ?

I've done a lot of staining. I've never seen anything like that. I agree that you need to finish removing whatever that is and treat the newly cleaned area as you did the lower part. Now you will have a uniform surface to treat. You might have to wait 'till Spring to complete this. The singles will 'season' a bit which will help with a new coating.

Many companies make semi transparent white. I like Cabot. You'll have to find some way to experiment.

My experience... worth what you're paying for it ;)

People love the faded silver-gray look of naturally weathered cedar, but unless you live on the coast and have salt air and a lot of sun, you can't get it naturally. In shadier, damper environments, natural cedar seems to always turn black.

It appears that someone used a semi-transparent/translucent stain/sealer in an attempt to get the silver-gray effect, but it still mildewed and turned black.

The paint store, they may be able to match, but it's hard to do so from photos, as the lighting greatly affects the perceived color. Indeed, your close up pic looks very different than the whole side of house pic. So maybe if you could bring in a single shake from one of the the top most courses (where it can be can easily be nailed back in place), you'll get a better match.

FWIW, I've always used Opaque stain on Cedar, both natural grade AYE and the finger joined and primed (FJP) stuff, as it's hard to prevent the black mildew no matter what, and I can pressure wash the Opaque and it looks great.

You will probably have to strip off the old sealer with something like MD80 or Ripit then neutralize with some oxallic acid before you use a sealer on it. Look into ReadySeal or Armstrong Clark Oil based sealers.
I don't know what cedar safe stripper would contain

I suspect you can apply it either way, but I've always brushed it myself.

Many people pay the premium for cedar because they like the cedar look... so they seal it, or stain it with a translucent tint.

I pay the premium for cedar because I don't like vinyl siding and I want rot resistant wood siding. I sided our house 25 years ago with cedar and have yet to have a single clapboard rot.

I don't believe anyone mentioned cleaning the black mold.

JOMAX is what you want to use, IMO. I am facing the same situation and will use a second dose as required.
