World's simplest browser-based Portable Network Graphics (PNG) color mask generator. Just import your PNG image into the editor on the left, and you will instantly get a mask that shows which pixels contain color data on the right. In the options, you can adjust how sensitive the color detection is, change how the mask looks, and see how many color pixels the image contains. Free, quick, and very powerful.

This browser-based program examines a PNG image and creates a mask that shows where real color appears. A pixel is considered a color pixel when its red, green, and blue (RGB) values are not the same. If all three values are equal, the pixel is grayscale, meaning it has no color hue, only brightness. The mask clearly separates these two groups, so you can see which parts of the PNG contain color. The "Color Sensitivity" option lets you control how strict the detection is. At sensitivity 0, every pixel with unequal RGB values is marked as color. Increasing the value makes the filter more selective: near-gray tones like rgb(240, 240, 241) or rgb(1, 2, 0) can be treated as grayscale because their values are almost identical. This helps ignore tiny color shifts and focus on areas with noticeable color. You can also choose the mask colors. By default, color pixels appear in black and grayscale pixels in white, but you can change them to any colors you prefer. The "Keep Original Transparency" option controls how transparent pixels are displayed in the mask. When enabled, transparent and semi-transparent pixels appear in the mask with their original alpha values preserved. When disabled, transparent pixels are rendered using the color assigned to grayscale areas, since a fully transparent pixel has an RGBA value of rgba(0, 0, 0, 0). Also, you can see the total pixel count in the options, along with the exact number and percentage of colored versus grayscale pixels. Png-abulous!

In this example, we find color pixels in a PNG photo of a hand holding a matcha latte. We set the color sensitivity to 0 to classify all pixels with unequal RGB values as colored. The resulting black-and-white mask clearly shows that the matcha drink and the hand are made of colored pixels, while the background is entirely grayscale. The analysis confirms that 31.57% of the image (86,488 pixels) contains color data, while the remaining 68.43% is strictly neutral. (Source: Pexels.)
In this example, we check whether an image contains strong, saturated colors or only subtle tints. We use a bright sunflower PNG and gradually increase the sensitivity to detect near-gray tones. Even at a high sensitivity of 33, all pixels are still classified as colored, showing that the image is highly vivid and contains almost no neutral shades. The PNG also includes transparency, and with the "Keep Original Transparency" option enabled, transparent pixels remain transparent in the mask. (Source: Pexels.)
In this example, we use a color pixel mask to uncover a hidden message inside a PNG image made of keyboard buttons spelling the word "PASSWORD". We generate the mask with sensitivity set to 0, which separates colored pixels from grayscale ones. Although the image looks ordinary at first glance, the positions of the grayscale pixels form the characters of the real password. This separation makes the hidden password clearly visible.
