Sorry, I'm not at all sure what you might mean here.
Are you saying that your beer used to be good, when the sediment had a blue colour. But, after 6 months, the blue sediment turned green and the beer was no longer palatable?

I would stop drinking it. Unless the brew had a strange ingredient tha could cause the color, that's a bacteria or mold and blue/green bacteria/mold are an absolute red flag. I'd ditch it and clean the bottles and equipment thoroughly.

If it tastes wrong now, and with the weird colours, I'd ditch it.
You might consider sterilising the bottles, by heating in the oven, and not just leave it at sanitising. Can you provide clues about where it was stored, where you fermented it, were the bottles new or from commercial beers?

It's probably fine, but pigmented contaminants are more likely to produce poisons than non-pigmented ones. The greeny blue could have been an aspergillus which produces toxins that increase your risk of cancer, without it notably affecting the taste, so probably best to chuck it just in case.
