See the colour of a colour number

[Alien Technology]

I am debugging a program. It has lists of colour numbers that it has gathered.

What is an easy way to type (or copy and paste) a colour number onto a (program or webpage) screen and see what the color is?

Currently, I execute Auto Colour Aid (ACA) and type in the number to do this.

By the way, if one goes on the Internet and tries to find a solution (with Google), most of them use hexadecimal colour numbers, rather than decimal colour numbers.

Just use mufasalayer and write a script to create a layer of each color

Just convert the number to hex?

RGB or BGR both take up 24bits of data. 8 bits per channel, They are simply shifted into place:

int main()
{
    std::uint8_t R = 255, G = 0, B = 0;
    std::uint32_t Col = B << 16 | G << 8 | R;
    std::cout << Col << std::endl;
    std::uint8_t R2, G2, B2;
    B2 = Col / 65536 % 256;
    G2 = Col / 256 % 256;
    R2 = Col % 256;
    std::cout << (std::uint32_t)R2 << ", " << (std::uint32_t)G2 << ", " << (std::uint32_t)B2 << std::endl;
    // or
    std::uint8_t R3 = 0, G3 = 0, B3 = 0;
    B3 = (Col >> 16) & 0xff;
    G3 = (Col >> 8) & 0xff;
    R3 = Col & 0xff;
    std::cout << (std::uint32_t)R3 << ", " << (std::uint32_t)G3 << ", " << (std::uint32_t)B3 << std::endl;
    return 0;
}

This will open a website that displays the color for you.

{$X+}
begin
  var hex := IntToHex(some_color, 6);  //replace some_color with eg 255 (the color you wanna look up)
  Swap(hex[1], Hex[5]);
  Swap(hex[2], Hex[6]);
  OpenWebPage('http://www.hexcolortool.com/#'+hex);
end.

With this little script below, you can even check colors directly in Simba itself:

const
  COLOR = 2599013;
  WIDTH = 100;
  HEIGHT = 100;

var
  bmp: Integer;

begin
  bmp := CreateBitmap(WIDTH, HEIGHT);
  DisplayDebugImgWindow(WIDTH, HEIGHT);
  DrawTPABitmap(bmp, TPAFromBox(IntToBox(0, 0, (WIDTH - 1), (HEIGHT - 1))), COLOR);
  DrawBitmapDebugImg(bmp);
end.

Thank you, Lucidity, Kasi, slacky and Janilabo, for your quick and informative responses.

I studied each of the solutions. This study has increased my knowledge of colours and Simba.

Lucidity,

I researched mufasalayer. I gather that you are referring to TMufasaLayer as described in https://villavu.com/forum/showthread.php?t=110667 TMufasaLayer - Draw on any window!.

I browsed the thread. This is outside of Simba and a little more than I am willing to tackle right now. However, thank you for introducing it to me. (I especially enjoyed browsing the GitHub: https://github.com/Olly-/mLayer.)
