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
