Cool, much like the Photoshop color picker! 8-)

Two suggestions:
1. Click&drag on the spectrum is OK, however you can't just click right on the new selection as you can in the color wheel (well, it's more a color square actually

) Would that be possible to add?
2. Is it possible to send a trigger to the output so whatever is connected to it will be updated every time you select a new color? (Dunno if that would be a reverse trigger because yellow connections work backwards)

I even wanted it to have a button to switch between properties and panel view, but Ruby doesn't allow that and I wanted it to stay 100% Ruby. I will support two versions from now on. (btw, for the panel view version I thought about using a sample and hold after the color mixer, so that the module could be set to purgable.
It is something for GURU, I just wanted to wait until all features are implemented. As soon as color palette (to store colors) is implemented I run out of ideas, so I think I'll transfer it to GURU then.

1. Done. Will be in the next version.
2. It already sends a trigger each time the color is changed (you may want to add a trigger counter to check for this).

EDIT: Added a schematic showing the triggering in action.

Also, if there are more ideas - they are more than welcome. If you are not experienced enough in Ruby, just tell your wish here. Maybe it can be realized! If nothing gets posted here, I assume it being the perfect Ruby-based Color Mixer

New version r4!

A color palette to store colors added. Also, it is now hosted on Flowstone GURU: http://flowstone.guru/downloads/generic-color-mixer/

There's always HSL color format if you could figure it out. Not sure if it would be worth all the trouble, but I find it useful for tweaking existing colors to lighter or darker as I think it simulates "colored light" effects a little better.

Speaking of which, I highly recommend adding an input to set the editor to an existing color.

If possible I would also add a way to open the Windows color picker, just for convenience sake, perhaps when clicking on the small color preview box.

I usually prefer knobs as a visual readout of a setting over the tumbler-readout style control, but seeing the indicator move across the gradient square makes up for it. I quite like that.

The hex setting can be "scrolled" with the mouse like the others, but the effect doesn't seem to be useful. It just looks rather glitchy. Not sure if there is meant to be functionality there.

As feedback on the color banks, simplicity is good but I find it too easy to accidentally click the wrong mouse button, which (to use hyperbole) could be disasterous. This is why in my design I used individual "set" and "get" buttons, even moved them apart so they couldn't be misclicked. It takes more UI space but I find this sort of thing necessary.

I also notice that the Hue value reads out to one decimal place. Would that not be an integer value as well? Maybe it's not, I just prefer working with integer values whenever possible with these things as they're a lot less "messy" and easier to keep track of and type in. Not a huge deal.

I believe you can simply attach a last-switched module before the output to hold the color value even if everything else is purged.

Just my nitpicks.

I think it's quite good though, nice work.

very neat solution with the colorpalette tulamide, thank you!

as it has a palette now it would be great to:

1. have an option to make the palette bigger maybe 6, 12,18

2. to provide a simple color selection module where you can choose from the palette

so you can use it as a central colorpalette creator and select the colors whereever you need them,
i did a fast mod which includes the palette size selection and a colorselector tool as long it is used like in the example
the main module can be purgeabled, its just a fast mod hope there are no bugs inside, and maybe it could be done different too..

Thank you once again, PHI

As long as I find any code examples in any language I can implement whatever color model there is (YMCK, YUV, HSL, HSI,...). But it's also a question of real need. I will think about it, but I don't want the color mixer to be bloated. Btw. HSL is pretty easy to get from HSV. V is [r, g, b].max while L is ([r,g,b].max + [r,g,b].min) / 2 (with r, g and b normalized)

The intention for the color mixer is to be a replacement of the windows color picker, so I won't add a link to it.

I already talked about it, so I just quote myself :mrgreen:

If you restrict yourself to hue only as an integer, you will miss a lot of colors. In fact, there's already a huge inaccuracy by restricting it to one decimal place. Colors are not so willing to sit on exact integer degrees

Wonderful! This is such a nice idea! Having a central place on the top layer to manage the colors, while just selecting one from a palette in lower layers. That will make it so easy to keep track of the coloring even in very large projects. And later changes are just a matter of seconds. If you don't mind, I will implement it and work out a way to have more palette options regarding this.

I could understand that, however, it doesn't seem to be random at all, rather it seems to only give you many shades of either light blue (180 hue) or red (0 hue).

Well, 255 * 255 * 360 = 23,409,000 possible colors, for example. As a developer and a human that's probably already a good bit too many. Having "every" color available is important for things like drawing gradients, but "color picking" is an entirely different thing. If I can't perceive the difference between two colors I would much rather they were one color!

I like Nubeat's concept too. Since you could tweak the color scheme of your whole schematic that way I would want a way to save and recall different working palettes though. For example I would want to copy the existing palette, tweak it, and then compare and if necessary revert to the original.

If you could add the inputs to set the colors like I suggested then you could perhaps accomplish this by loading a separate color mixer module and setting the new one by connecting it to the old one, though you'd then have to manage conflicts with the wireless links (maybe just an on/off switch).

What color you get out depends on where you start from, and if you use 'shift' or not. It will always be one of two hues in different shades.
Remember, this is just an offer, no one needs to use it

There's a misunderstanding of the color concept. Since we are on a monitor, we always stay in the RGB color space. The total number of colors is the product of all 3 color channels. A channel has 256 variants (0-255), so the total number of colors in the 8-bit-RGB is 256*256*256 = 16,777,216. HSV color space is much more accurate than RGB with its only 256 steps per channel, so can easily map them. But of course, they don't fit on integer steps of hue. For example,

Code: Select all

rgb 62,24,160

can be mapped to

Code: Select all

hsv 256.8,0.85,0.627

The real values have a lot more digits, so this is already just an approximation. If we now take 256.8 and make it an int, it would be 256. But

Code: Select all

hsv 256,0.85,0.627

represents

Code: Select all

rgb 60,24,160

And if we round hue instead of just converting to int, we would get 257. But

Code: Select all

hsv 257,0.85,0.627

represents

Code: Select all

rgb 63,24,160

As a result, by restricting hue to integers, we wouldn't be able to map all rgb colors. We already lost at least 3 colors just in this example. And this is important because there's not only human eyes. What if you trace a certain color? The computer will look for rgb 62..., but since hue was restricted, never finds it.

Don't forget that the color palette is bound to the schematic it's in. It's persistent per project, so to say. But I also thought in the direction of grouping colors. Let's see what I can come up with!
