Description

Simple color mixer. You can change the number of segments of the gradient control and move the slider or enter a percentage to get a desired blend of two colors in RGB or HSV color space. The width of the dialog can be changed.

Color Mixer UI

I made this script because quite frequently in the past I had to reach for Photoshop or Mix color map just to find a value somewhere in-between two colors. This control offers more intuitive way of blending them and more control over the result. The two source colors and the resulting blend color are colorpickers and as such you can right-click them and copy/paste their values.

For newer max versions (starting with max 2020) you can use the colorMixerQt.ms file instead:

Installation: The .ms file can be run from any location (Maxscript -> Run Script...). If you want to put it in toolbar, menu or quadmenu, you can create a macroscript using Macroscript Creator.

Well, the time has come.. Max 2024 deprecated IDisplayGamma and removed its' properties.
Max 2024 has a Color Converter Utility.

For max 2024 you can use the colorMixerQt.ms file which shouldn't have this issue.

Excellent!

Thanks for updating this, appreciated.

I wonder though if this code seems a little redundant maybe? 


on cpResult changed val do
    cpResult.color = getColorAtPos (int(dncTriBtn1.pos.x - 105))

It kind of says, "when I'm changed, change me again"

I've put that line into the next event handler down so that changing the % spinner value changes the output colour.... 


on spnPercent changed val do
(
	local ctrl = btn_controls[(0.01 * btn_controls.count) * (100 - val) + 1]
	dncTriBtn1.pos.x = dncTriBtn2.pos.x = 106 + ctrl.Location.X + ctrl.Width/2
	cpResult.color = getColorAtPos (int(dncTriBtn1.pos.x - 105))		
)

Best regards.
MrTom.

Cool, thanks for spotting that :) I've included that bit in the refactored version, if you spot any other problem/oversight, don't hesistate to let me know, I really value that.

IIRC it was there to prevent one from accidentally changing the result color but it was a stupid decision eitherway :)

Fixed, I think....?

MrTom · 2013-10-18

Further to my last post I think I have found the error....

Changed: 


fn getStepColor clr clr_step mode =
	case mode of
	(
		#rgb : gammaCorrect (clr + clr_step) gamma
		#hsv : gammaCorrect (hsvToClr [clr.h + ............
	)

To: 


fn getStepColor clr clr_step mode = 
	case mode of
	(
		#rgb : gammaCorrect (clr + clr_step) gamma
		#hsv : gammaCorrect (convertHsv2rgb [clr.h +  ............
	)

Is this correct? It seems to work ok.

I did find a couple more [ minor ] issues though in the process, see image for details.

Regards.

Error.

MrTom · 2013-10-17

Ran the .ms script from editor...all fine until I click the HSV button.
The image shows the error produced.

I acknowledged the error and closed the rollout.
Ran the script again and the same error occurred instantly.

Closed Max and re-opened, ran script again....instant error again.

Using:
Win 7u SP1 x64
Max 2013 pu6 x64

Regards.

Updated

Swordslayer · 2013-10-17

Thanks for using it, I've updated the script to handle gamma correction.

obaida · 2013-10-17

its working fine now , thank you for quick replay .

I think it's overwritten another of your scripts.

Hi,

I've just installed this script by dragging the .mcr file in to max. When i go to customize user interface, the only thing listed in the advanced drop down is Render Info Strip, when i drag this on to a toolbar and run it, it open the color mixer!

Could you check this scripts .mcr to see if this is true or not.

Cheers.

My mistake

Swordslayer · 2011-08-31

You are right, I've attached the corrected version now.

No problem.

Script_Butler · 2011-08-31

Thanks for sorting it asap.

Swordslayer · 2011-08-31

Thanks for input, I will look into it ASAP.

Nice!
