2D Image Blend Mode
Blend Mode dictates how two colors are combined to produce a final pixel.
| Normal | Edits or paints each pixel to make it the result color SrcAlpha, OneMinusSrcAlpha. |  |
| Darken | min(a,b): Looks at the color information in each channel and selects the base or blend color, choose whichever is darker as the result color. |  |
| Multiply | a*b: Looks at the color information in each channel and multiplies the base colors by blend colors. |  |
| Lighten | max(a.b): Looks at the color information in each channel and selects the base or blend color whichever is lighter as the result color. |  |
| Screen | 1-(1-a)(1-b): Looks at each channel’s color information and multiplies the inverse of the blend and base colors. The result color is always a lighter color. |  |
| Burn / Color Burn | 1-(1-b)/a: Looks at the color information in each channel and darkens the base color to reflect the blend color by increasing the contrast between the two. |  |
| Linear Burn |  | |
| Dodge / Color Dodge | b / (1 – a): Looks at the color information in each channel and brightens the base color to reflect the blend color by decreasing contrast between the two. |  |
| Linear Dodge |  | |
| Add | a+b: Looks at the color information in each channel and brightens the base color to reflect the blend color by increasing the brightness. |  |
| Subtract |  | |
| Overlay | Patterns or colors overlay the existing pixels while preserving the highlights and shadows of the base color. |  |
| Soft Light | The effect is similar to shining a diffused spotlight on the image. If the blend color (light source) is lighter than 50% gray, the image is lightened as if it were dodged. If the blend color is darker than 50% gray, the image is darkened as if it were burned in. |  |
| Hard Light | If the blend color (light source) is lighter than 50% gray, the image is lightened, as if it were screened. This is useful for adding highlights to an image. If the blend color is darker than 50% gray, the image is darkened, as if it were multiplied. |  |
| Pin Light |  | |
| Linear Light |  | |
| Vivid Light |  | |
| Hard Mix |  | |
| Average |  | |
| Difference |  | |
| Exclusion | Creates an effect similar to but lower in contrast than the Difference mode. Blending with white inverts the base color values. Blending with black produces no change. |  |
| Negation |  | |
| Phoenix |  | |
| Reflect |  | |
| Snow Color |  | |
| Snow Hue |  |
