Final answer:
The blend mode that ignores white is the Multiply blend mode, commonly used in graphics editing software to allow darker pixels to affect the layers below while white pixels remain transparent.
Step-by-step explanation:
The blend mode group that ignores white is the Multiply blend mode. In graphics editing software like Adobe Photoshop, blend modes control how two layers blend with each other to produce various effects. The Multiply mode has the characteristic of ignoring white, meaning that white pixels on the active layer do not change the appearance of the pixels on the layers below. Conversely, any darker pixels will darken the pixels on the layers below based on their luminance values. For example, if you have a black and white image on one layer and a photograph on another, using the Multiply blend mode will result in the photograph being visible through the black areas of the image, while the white areas will become transparent.
