BACK_COLOR for True colors doesn't seem to work when I try with 5.0.0 about jcolor

Thanks for reporting it. I have limited time now, but I soon as I have a break I'll try to reproduce it.

No problem! Take your time 👍

Thank you for waiting. I tried to reproduce your issue using the code you showed in your screenshot:

        Thread.currentThread();
        Random _rand = new Random();

        System.out.println(colorize("This text will be yellow on red", BRIGHT_YELLOW_TEXT(), RED_BACK()));
        System.out.println("\n");

        System.out.println("Use Case 7 - Any TrueColor (RGB), as long as your terminal supports it:");
        for (int i = 0; i < 5; i++) {
            Attribute bgCol = BACK_COLOR(
                    _rand.nextInt(255), _rand.nextInt(255), _rand.nextInt(255));
            System.out.println(colorize("Test: " + i, bgCol));
        }
        System.out.println("\n");

Your code is actually very similar to "use case 7" of my documentation, so it's a scenario I tested before releasing the TrueColors feature.

I ran it inside IntelliJ CE and as you can see from my screenshot, the terminal displayed the background with TrueColor (8-bit) colours.

Mind that for TrueColors to be displayed your terminal needs to support it. Which terminal did you use?

I'm not sure if Windows Command Prompt (cmd.exe) supports TrueColors. I saw this update but it's about "Windows Console". When they say "Console" are they referring to "Windows Command Prompt" or their new shiny "Windows Terminal"? 🤷‍♂️

Can you please try to run your code on PowerShell? Or Windows Terminal?

Hi!

Yes I ran the code on Windows cmd console as well as the power shell console window and the background was not getting highlighted in both cases. Maybe this is a windows limitation as you pointed out. Unfortunately I want to run my code on the console only for now (as opposed to some IDE console like eclipse or IntelliJ so. Thanks for your support!

Oh bummer 😞

Before we give up, let's try one to figure out what's the cause of the issue:

• What is the Windows 10 build you're using?
• From your output screenshot format, I assume you are running your app with Maven. Could you try generate a jar of your app, and then use java to run it directly (without mvn)?
• Just for sanity sake, could you import your code to an IDE (i.e. IntelliJ), run your code there and check the IDE's terminal output?

Here some more output:

1. dos command line
   

2. power shell:
   

3. Eclipse IDE (cannot run from IDE as it required some parameters to be set in the environment which I am too lazy to do right now. I can do it later if necessary. Thanks!

1. I checked your Windows 10 build and 14393 is fairly old, from 2016. I'm running 19041, from 2020. Not sure that makes any difference, and it would be a big change for you, so let's ignore that.
2. Even PowerShell fails to show color... so it's unlikely a Windows issue. The remaining suspects are Maven and JColor.
3. Yes, please try it but take your time.
