How can i make a rainbow color function?

[TrashBoat]

Could someone help me create or give an idea of how to do a incrementing for loop that would do this: https://i.imgur.com/YFUt47H.gifv

I'm having a hard time figuring it out :S

Hello,

you can use multiple whileloops

expandcollapse popup

#include <Color.au3>

Local $RGB[] = [ 255, 0 , 0]
Local $SleepTime = 10

$hGUI = GUICreate("test", 100, 100)
GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
GUISetState(@SW_SHOW)

For $i = 1 To 10
    While $RGB[1] < 255
        $RGB[1] += 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd

    While $RGB[0] > 0
        $RGB[0] -= 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd

    While $RGB[2] < 255
        $RGB[2] += 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd

    While $RGB[1] > 0
        $RGB[1] -= 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd

    While $RGB[0] < 255
        $RGB[0] += 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd

    While $RGB[2] > 0
        $RGB[2] -= 1
        GUISetBkColor(_ColorSetRGB($RGB), $hGUI)
        Sleep($SleepTime)
    WEnd
Next

Thanks! That works perfectly

Might also help using HSL color space:
