Unable to Find Source Of Code Error

This might be the silliest question of the day in this forum, but this is driving crazy. I'm working on an app, and when I run the app I keep getting an error saying that "The argument to the 'ColorValue' function does not represent a valid color value".

I get nothing when I run the 'App Checker":

Is there a way to check the entire code without going element by element checking any property that has to do with colors (color, fill, etc.)?

 

The error doesn't show up when I'm running within PowerApps Studio, only when is live.

Thanks.

Hi @emfuentes27,

 

I think the Power Apps search pane will be able to help you further.

This gives you the option to search by variable names, collections, function... within you app's code.

 

I will link the search pane documentation here.

 

I hope this helps!

Yes, I did. In my particular case the issue was that I was adding the Alpha Values to the Hex Code Colors. (Eg. (ColorValue("AAAAAA") vs ColorValue("AAAAAAXX")). XX represents the alpha values. For some reason PowerApps didn't like that. The funny thing is that I've been using alpha values for a while, and then stopped working. I haven't used alpha values again, so I don't know if that was just a bug.

Thanks @LaurensM  I never noticed nor used that feature.

Hello, did you manage to stop this error showing when you open the live app? I've got the same, all my ColorValues are valid in my Onstart, when I click next to them it show me which color it is etc. I'm out of ideas. Tried only having a small amount of the code, it still produces this error

Thanks for responding 🙂 That correlates with the cause of my issue. I have a side menu component that had alpha values so it's obvious which icon is the current page you're on because it'll have a transparent color ontop of the icon. I started removing one component at a time, then testing and removing the side menu sorted the problem. It displays correctly so this must be a bug Microsoft need to fix. If I find a way that lets me use it without the error showing in the mean time, I'll reply to this thread for others who come across the same issue 🙂

I started using RGBA values for color instead, and it works just fine.

I had the same problem, all I wanted to do was converting a color defined with ColorValue(#0055FF) to another color with a specific alpha value.

My workaround (probably not the best solution, but working)

 

RGBA(
    Hex2Dec(
        Match(
            Substitute(
                Match(
                    JSON(
                        // The Color where you want to change the alpha Value, here: ColorValue("#0055FF")
                        DS_Segmented_Control.SelectedFillColor,
                        JSONFormat.IgnoreUnsupportedTypes
                    ),
                    "#[a-fA-F0-9]{6}"
                ).FullMatch,
                Match(
                    Match(
                        JSON(
                            // The Color where you want to change the alpha Value, here: ColorValue("#0055FF")
                            DS_Segmented_Control.SelectedFillColor,
                            JSONFormat.IgnoreUnsupportedTypes
                        ),
                        "#[a-fA-F0-9]{6}"
                    ).FullMatch,

                ""
            ),
            "[a-fA-F0-9]{2}"
        ).FullMatch

    Hex2Dec(

                ).FullMatch,
                Match(
                    Match(
                        JSON(
                            // The Color where you want to change the alpha Value, here: ColorValue("#0055FF")
                            DS_Segmented_Control.SelectedFillColor,
                            JSONFormat.IgnoreUnsupportedTypes
                        ),
                        "#[a-fA-F0-9]{6}"
                    ).FullMatch,
                    "#[a-fA-F0-9]{4}"
                ).FullMatch,
                ""
            ),
            "[a-fA-F0-9]{2}"
        ).FullMatch
    ),
    // Alpha Value
    0.25
)

 

You have to write your Color 6 times inside this formula (Replace "DS_Segmented_Control.SelectedFillColor" with your color)

This Code splits the #0055FF color into its 3 parts (red, green, blue) and uses hex2dec from PowerApps to convert it into RGB Values ranging from 0 to 255 which can then be used inside the RGBA() Function with a specific Alpha Value (here 0.25)
