Something Is Coming... And It Makes Working With Colors A Real Joy :)

[Mathieu]

At last! 

...color palette management, color transitions with any number of points, easy way to sync hue, saturation and intensity attributes to give the desired colors, specify RGB colors... But what is it? 

Let's start with the color palette, allowing to manage all your project's colors in one place. You can create solid colors and complex gradients. Update something here and all linked hue, saturation and intensity attributes are updated immediately.

Here's the color editor. Yes you can specify a pure red easily with the RGB controls! You'll also be able to explore the HSI/RGB mapping and hopefully, better understand what's going on. When creating a gradient, you see the preview right here and your lights are also updated as you make your changes. Live preview! 

Finally, you can select all your color attributes at the same time (hue, saturation, intensity) and simply select a color in your palette. One click! When selecting a solid color, the result is easy to guess. When selecting a gradient, the source's power will generate the transition from 0% to 100%. You can control the color transition very precisely and avoid turning around the whole color wheel! 

This is coming soon in the new beta. I can't wait to get some feedback!

Cheers,

Mathieu

I have a very good feeling about this. The screenshots look promising.

On the other hand, I'v never used the hue shift stuff and so before.

 

Looks like you can define a path that makes up a color palette. That would be very cool.

I'm thinking of an orange mood that can turn to pink. Valentine's day is coming.

Mathieu, 

This looks AWESOME, can't wait to get my hands on it!  I hope this comes from some of my suggestions... as always, THANK YOU!

The only thing I don't see in it is adding capability for RGBW, RGBA, RGBAW etc... lights.  I personally LOVE having access to my white LED's.  I often randomly strobe them for flare or flash type of effects.  Or just want a pure COOL white for specific effects.  

Any word on when this will be out?!   

Can't wait to see what's next!!!!!!

Keep up the good work!

Hi Nick,

For RGBW, Lightjams takes care of the white channel the best as it can. The closest the saturation is to 0%, the higher is the white level. If you want to control it manually, you can just patch a RGB fixture followed by a dimmer attribute for the white.

For RGBA, Lightjams doesn't handle the amber automatically right now, due to calibration issue across manufacturers. So you need to control it with another attribute. 

The new beta is coming in the next few days.

Very nice !! 

This makes it so easy to create palette's. Compared to the relatively static palette before, this gives many options.

Great job and well done. A big improvement in color handling.

Hi Mathieu,

This is really cool and I like it a lot. You've just sentenced me to putting in the RGB values of all my favorite gels. :-)  I do have a question, how do you fade them on and off? I tried making a gradient black to red. With the Source's Power at 0% it is black, at 1% it's dim white/pink. As I work up to 100% it turns more red but there's never a point where the red stays red as the power goes up and down. If I have a single color, turning the Source's Power up or down does nothing. Is there a way to fade it to black?

Great job on this, it'll really save a lot of time.

Thanks,

Derek

Hi Derek,

To fade one color to black, just don't link the intensity attribute to the color palette. Let it go from 0% to 100% and control it with a source.

[Mathieu]

I've uploaded a new beta. There's now an easy way to create a loop when using multiple colors. Also, I've added a function: grid.colorGradient.loop(x,y,goNext). It loops through all colors of the gradient of the attribute at the specified position (x,y). 

For example, you put a source just under a hue attribute and use this power formula: transition.circular(0.5, grid.colorGradient.loop(x,y,pulse(1))). Each second, this will go to the next color, doing a 0.5s fade. Using the transition.circular makes sure that when we're starting over (going from 100% to 0%), we're not doing a fade out but just going straight to 0%.

By the way, the formula used in the 3rd screenshot to map all colors of the gradient is just: px. Using the shader mode, only one source is needed. The px variable returns the percent corresponding to the current horizontal position. 

Cheers,

Mathieu

Hi Mathieu,

Ahh, I thought all 3 (HSL) had to be selected and run off a single Source. Doing it as you described...yup...there it is, working. 

My kitchen is now RoscoSun 85. Ooh! One click, now it's Bastard Amber.

Very cool.

Thanks again.

The link doesnt seem to be working :((( I'd love to download and try out these new easier to work with gradients!! looks like it could be the perfect tool for my upcoming show. any chance of getting it back up??
