Completely Random Font Colours For Graffiti Wall

Open "wall.php" and find:

PHP Code:


		
			
    $randcolor = rand(1,9);

    if ( $randcolor == 1 ) $color = ImageColorAllocate($myimage, 255, 255, 0);

    elseif ( $randcolor == 2 ) $color = ImageColorAllocate($myimage, 255, 165, 0);

    elseif ( $randcolor == 3 ) $color = ImageColorAllocate($myimage, 255, 20, 147);

    elseif ( $randcolor == 4 ) $color = ImageColorAllocate($myimage, 255, 0, 0);    

    elseif ( $randcolor == 5 ) $color = ImageColorAllocate($myimage, 255, 255, 255);            

    elseif ( $randcolor == 6 ) $color = ImageColorAllocate($myimage, 0, 255, 255);            

    elseif ( $randcolor == 7 ) $color = ImageColorAllocate($myimage, 255, 0, 255);            

    else $color = ImageColorAllocate($myimage, 0, 255, 0);

and replace with

PHP Code:


		
			
    // +++ completely random colours

    $randred = rand(1,255);

    $randgreen = rand(1,255);

    $randblue = rand(1,255);



    $color = ImageColorAllocate($myimage, $randred, $randgreen, $randblue);

    // --- completely random colours

now save and upload and you're done :)

would be good to add a button on the wall entry field to select a random or not... this is good feature!

The problem on my board is that it generates too many dark colours. Fix it by having the random value from 150-255

Code:

// +++ completely random bright colours

    $randred = rand(150,255);

    $randgreen = rand(150,255);

    $randblue = rand(150,255);



    $color = ImageColorAllocate($myimage, $randred, $randgreen, $randblue);

    // --- completely random bright colours

While developing the Wall I found that random colors didn't render well and I got alot of purple or brown even when it was trying to render some off yellow color. Sticking close to primaries will ensure as close as possible colors.

    $randgreen = ceil(rand(1,85) + ceil(rand(1,170) / 2) + rand(1,85));

    $randblue = ceil(rand(1,510) / 2);

but really i'm just playing with it.
