Hi over the next few weeks i'll be experimenting with different color changing stars..For use in spherical shells..

Anyone got some suggestions on good colors/types to use? i have just done a very simple Red to Blue then Blue to Red .All organic fueled .. im waiting for them to Dry....Shimzu mentions using complementary colors??? :blink: Also things like willow to glitter will glitter to willow look good? or Flitter to Red,Blue,Green Etc...Also when making tiger tail ,Willow, Chrysanthamum Mixes is it best to use Pine charcoal?..

thanks

Complementary colours are colours that are opposite each other on a colour circle. Coincidently, I stumbled across this link yeaserday

To answer another question, sasman: Pine charcoal isn?t the only charcoal to get nice sparks. But it is the only charcoal, which gives needle-shape sparks which spark itself. (hard to describe). Different charcoals give different shaped sparks. I often use poplar charcoal. This gives longlived sparks, too.

also, on color changing stars, you need to layer the chems. so when you first make the star, let it dry, and then dip it in star sludge of a certain color. let it dry. repeat with a different color as neccesary.

The effect you describe is called "double branching" and is easier to get with high carbon iron. Only very specific pines give this effect (not common to most verities in Europe), and there are other trees who give the same effect with better quality.

SASMAN is rolling his stars, which layers them quite nicely - there's no dipping involved. I would try an orange to purple, or purple to orange - never seen that particular colour change.

I always like a shell that bursted dark for about 2 seconds. Then after a few people start thinking nothing is happening WOOSH nice golden willow starts floating down. Then you could have it go into some nice blue cores.

Seen combos of Dark to Willow or Willow to blue core but never all three. Just one of my ideas I would like to see :D .

Sorry to be off-topic and if you feel I should post this in the star formula thread I will. I believe Pine Charcoal gives more of a reddish-orange effect, what types of woods make the nice golden effect seen in alot of FreakPyroManiac videos where 10's of them are fired at a time to fill the sky with gold?

As a general tip, consider brillance and saturation as well as color.

Assuming your blues are less bright and saturated than your greens, which are brighter but less saturated than your purples which are as bright but not a saturated as your reds, or some such order. You are going to want to consider the order as well the combination. I'd love to do a star that went Red/White/Blue, but noone would be able to see the blue after the bright red has them seeing a green after image and the white has desensatized thier vision B) . Whereas Blue/Red/White would be distinguishable and get progressivly brighter.

This site has some great colorwheels and quick explanations but keep in mind they're talking pigment, not light (mix green and orange light get yellow, mix green and orange paint, get brown, lights an additive process, pigments are subtractive)

A few suggestions:

modified crys6 to red or blue
Crackle to blue
Tigertail to silver
glitter to red
Red to white

Well I can say don't do a colour change from silver streamer to granite!
The comp was

Meal 75
Al 20
Dextrin 5

The granite doesn't go green sort of white on the ground but doesn't burn up in the air. They have been drying for over 2 weeks so I know its not moisture. I will use an intermediate layer next time.
