Using RGB to get desired colored stars

[NightPainter]

I'm going to try combing red (Strontium Carbonate), Green (Barium Carbonate) , Blue (Copper Carbonate) to get a deep pink colored star.

 

R G B

255;20;147

 

Using this color table http://web.njit.edu/~kevin/rgb.txt.html and one of the red rubber star formulas I came up with this formula.

 

Potassium perchlorate 0.3

Magnalium 0.3

Strontium carbonate 0.12

Barium carbonate 0.01

Copper carbonate 0.07

Parlon 0.15

Red Gum 0.05

 

Acetone

 

It's going to be a few days before I can mix it up and test it.

 

 

I'm also going to try a modified formula from the rubber star formulas

 

Potassium perchlorate 0.335

Magnalium 0.335

Strontium carbonate 0.15

Parlon 0.13

Red Gum 0.05

 

My thinking was that if I combined the white and red start formulas I would get pink. I increased the Magnalium and Potassium Perchorate and decreased the Strontium Carbonate and Parlon from the original Red formula.

 

 

 

I was wondering if anyone sees any reason why I should not give these two experimental formulas a go or has any suggestions.

 

Thanks

Im not into colored stars just yet, give me another year or so. I understand its fun to experiment and learn from the result, but if you really want a deep pink star you could just use the Veline color system that is already tried and proven. Using the Magenta comp. would give you a nice deep pink. Edited May 13, 2011 by Pechovski

It's worth a shot, but I don't think that second formula will be of much success. The white formula is white due to a lack of colorant, not because it purposefully gives off white light. The second formula is going to be probably just about as red as the original. If you want a pink, try swapping out 30-50% of the SrCO3 for magnesium carbonate. Alternatively you could probably drop the perchlorate to 20, and use 10 parts potassium nitrate. Maybe a swap of 5 instead of 10? It's hard to tell. I spent a long time developing a pink I like, and can whole heartedly say that it is much more difficult to do in practice than in theory. I found the best way was to wash out a red. It's easy to over or undershoot though.

I'm waiting for an order of KClO_{4 before I can start experimenting.}

Pechovski,

 

With the little KCIO4 I had left took your advice and I made a small batch veline's Magenta, very nice color.

 

Mumbles,

Thanks that is exactly the type of suggestions I was looking for. I will make up a batch of the RGB formula and report back on my results.

 

Thanks

I find this to be a quite nice Magenta as well. It probably wouldn't be hard to turn it more pink. I might even try replacing all the perchlorate with potassium nitrate and see where that leaves you.

 

Strontium Nitrate - 38

Potassium Perchlorate - 8

Parlon - 18

Magnalium - 12

Copper Carbonate - 10

Charcoal - 5

Sulfur - 5

Dextrin - 4
