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

// +++ 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.

i've been playing with this, it's a matter of php's favouritism to certain numbers, i've been trying to circumvent this with

PHP Code:

    $randred = mt_rand(1,255);
    $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.
