FlaMtnBkr Posted November 30, 2014 Share Posted November 30, 2014 (edited) A good yellow is a mix of red and green. A formula where barium and strontium are exchanged would be a good starting place. Like independence red/green or the red rubber stars. 55 parts green and 35 parts red is a good starting point and adjust to your tastes. This is an optical yellow versus a sodium yellow and should be closer to the lemon yellow you're looking for. Edit: no, they don't add up to a 100 Edited November 30, 2014 by FlaMtnBkr 1 Link to comment Share on other sites More sharing options...
Col Posted December 5, 2014 Share Posted December 5, 2014 75% green and 25% red produces a decent yellow, if you push the red percentage up you can get a half decent orange.http://youtu.be/oL914kpVqqw Link to comment Share on other sites More sharing options...
rogeryermaw Posted December 5, 2014 Share Posted December 5, 2014 mr niladmirari was referring to a mix of the colors from this thread. http://www.amateurpyro.com/forums/topic/9416-color-mix/ Link to comment Share on other sites More sharing options...
Mumbles Posted December 6, 2014 Share Posted December 6, 2014 As far as mixing colors, I use about 62:38 Green:red for my yellows, and 45:55 for my oranges. You can play to get the hues you like. It may depend a little on which formulas you're using too. Let us know how they turn out. Link to comment Share on other sites More sharing options...
GalFisk Posted December 10, 2014 Share Posted December 10, 2014 Veline yellow (55 Veline green, 45 Veline orange) also gives you a lovely lemon yellow: http://www.pyrodata.com/compositions/Velines-yellow-starThe formula is more complicated than the above suggestions, so it usually only makes sense if you're doing Veline colors anyway. I've only tested a little of it, but I really liked the color - not greenish at all, and not sodium-yellow. Plus, it uses cheap-as-dirt calcium carbonate (chalk) instead of strontium. I imagine that this makes it easier to fine-tune the color as well, as the range is smaller. 1 Link to comment Share on other sites More sharing options...
whatknot Posted December 10, 2014 Share Posted December 10, 2014 This may do the trick for you; I got tired of "sodium amber" and tinkered with the addition of "barium green". The formula can be rolled or cut, 35% alcohol works great, but a graded prime is recommended (or a hot inner prime). The hexamine may be ommited but it does help intensify the color a bit.

FlaMtnBkr Posted December 11, 2014 Share Posted December 11, 2014 Wouldn't that still be a sodium yellow with all that cryolite in it? Link to comment Share on other sites More sharing options...
Mumbles Posted December 11, 2014 Share Posted December 11, 2014 The hue will be different than the typical bare sodium yellow, which is really what most people want to avoid. Link to comment Share on other sites More sharing options...
whatknot Posted December 12, 2014 Share Posted December 12, 2014 As much as we see streetlight "sodium" lights I like to avoid bare sodium yellow too! From some ole notes a formula with no perch, 58% Ba(NO3)2, and 7% cryolite produced a yellow-green... the formula posted, however, produces "a pretty deep color, real lemon yellow- not amber, fast burn, and for some reason having both sulfur and hexamine intensifies color." It has been a while since these were tested but any feedback is appreciated!! Link to comment Share on other sites More sharing options...

karvannan Posted March 31, 2015 Share Posted March 31, 2015 any other lemon formulas without kp please let me know we use kno3 not kp Link to comment Share on other sites More sharing options...
nt8 Posted March 31, 2015 Share Posted March 31, 2015 any other lemon formulas without kp please let me know we use kno3 not kpi don't think, that you get good lemon yellow with KNO3. If you want to use nitrates, try to combine barium and strontium nitrate, or barium-nitrate and cryolite/oxalate. green composition + 5-8% cryolite or oxalate. Try Gary Smith's parlon yellow, or Ned Gorski's brillian yellow. Link to comment Share on other sites More sharing options...

lloyd Posted May 29, 2016 Share Posted May 29, 2016 I'm sure I've mentioned this, but I prefer "optical" yellows... barium/strontium blends. They can be tuned to any shade along the green to red line, including some really 'sassy' yellows. LLoyd Link to comment Share on other sites More sharing options...

lloyd Posted August 1, 2016 Share Posted August 1, 2016 Eh... add a chlorine donor and some barium nitrate, and you'll be able to tune the color anywhere from green through the yellows and oranges, all the way to red. And you'll be able to choose your favorite hue. What you cited does make a yellow color, but I don't find it very pleasing with all those Ti sparks, unless that happens to be what you're looking for. To me, yellows are prettier when they 'stand alone', clean, with a fairly large flame envelope. Lloyd Link to comment Share on other sites More sharing options...
dynomike1 Posted August 3, 2016 Share Posted August 3, 2016 Yea it also depends what other color you have beside it. Sometimes another color can make a terrible color look good. Link to comment Share on other sites More sharing options...
