Below given programs illustrate the ImagickDraw::color() function in PHP:

Program 1:

<?php

//Create a new Imagick object
$imagick = new Imagick();

// Create a image on imagick object
$imagick->newImage(800, 250, 'white');

// Create a new ImagickDraw object
$draw = new ImagickDraw();

$x = 0;
while ($x < 900) {
    // Draw lines using imagick::PAINT_POINT
    $draw->color($x, 0, 1);
    $draw->color($x, 30, 1);
    $draw->color($x, 60, 1);
    $draw->color($x, 90, 1);
    $draw->color($x, 120, 1);
    $draw->color($x, 150, 1);
    $draw->color($x, 180, 1);
    $draw->color($x, 210, 1);
    $draw->color($x, 240, 1);
    $x++;
}

//  Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat("png");
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>

Output:

Program 2:

<?php

//Create a new Imagick object
$imagick = new Imagick();

// Create a image on imagick object
$imagick->newImage(800, 250, 'white');

// Create a new ImagickDraw object
$draw = new ImagickDraw();

// Set the fill color
$draw->setFillColor('green');

// Color the image using Imagick::PAINTFILL
$draw->color(1, 1, Imagick::PAINT_FLOODFILL);

//  Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat("png");
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>

Output:
