Fun with Firefly

 

Actually it's a bit more complex.  In the legacy mapped mode three commands are sent (one for R, one for G and one for B).  To go from red to green would involve ramping the red channel down while the green channel goes up.  Easy enough, but...

 

To go from red to yellow while simultaneously heading toward black is much more complex.  Red is a linear ramp from on to off, but green must come up and then back down in a parabolic shape.  It would start upward at the opposite angle of red but gradually change angle until it hits the "crossover point" where it would begin a gradual descent with increasing angle until it is 1:1 with red at the end.  Lacking such a "parabola" prototype in the protocol, there just isn't a way to send this.  It must be simulated by breaking it into multiple commands in the editor. 

What you desire (very creative BTW) would require a very complex curve in at least one of the color channels... to offload such calculations into hardware at a $160 price point might not be realistic.  The only way to accomplish this is on the Aurora side which would require Aurora to automatically send this as a series of colors.  If used too much this would bring the network to a crawl which isn't desireable either.

 

Step 1: FF0000 to C06000

Step 2: C06000 to 504000

Step 3: 504000 to 000000

 

This isn't perfect as the red channel really needs to remain linearized while the green channel needs to follow a curve.  The RGB tool stays in the linear domain because that is all the protocol allows for (to render this correctly would require hundreds of commands to be sent which would choke the network).

 

There will need to be at least 1 step for each 30 degrees in the color wheel (HSV value "H").  Unfortunately the timing precision of the ramps in the Firefly firmware isn't perfect (runs a little fast actually) so it looks like it "takes a breaK" at each step on the way down. 

 

Alternately, if this is a quick ramp you could render it as a series of "set color" commands.
