For starters, please hit enter between every couple of pictures you post. I'm on a widescreen monitor and your pictures still make the topic wider than my screen. You can edit your post - so it's not too late.
As for your color, I'd say you're moving in the right direction. The implosion looks pretty darn good. The silver colors can often (and usually do) develop a wispy look when imploded like that, but there are tricks to avoid that. Mostly they involve keeping your work nice and hot until you're done, and lots and lots of practice. For more color, you could also kiln strike it, which will develop the amber purple further. Kiln striking involves holding at 1050 to 1100 degrees (depending on your kiln) previous to your annealing cycle. Some people will strike multiple times, or for several hours, or both. There's a lot more to it, but that's the basics.
Kebira goes into some depth on kiln striking. In fact,
read the whole thread for lots of great information on boro color.
Check out vega's post in this thread for more on color in your implosions - I haven't tried this but I've seen his work so I'd say he knows what he's talking about.
As for haze - when you heat up a rod of amber purple in a neutral (or oxidizing) flame, you will see a hazy surface skin develop and then it will disappear, cooked away by the torch, as the amber purple goes transparent clear. That is what we call haze. It will re-develop if you let your piece cool too much, but it can (usually) be removed again by re-heating to molten, blasting with an oxidizing flame, or both. It is easier to keep the haze off in a slightly oxidizing flame environment. Some colors will haze no matter what you do - which is ok too, it's probably by design (Caramel Luster for example), so don't get frustrated.
As I noted before, I highly recommend Mr. Smiley's video for working with color.
