Blendmode Room Type

Learn about blend mode rooms here.

Blend mode rooms supply your room with more features to draw with, at the cost of removing layers. They create certain effects on your drawings or strokes that would otherwise be difficult to create. There are 11 different types and they will be explained here, however the best way to learn them is to use them yourself.

Blend modes

Normal: Your strokes will be normal, as if no blend mode was selected.

Add: This blend mode will lighten your drawings by adding the RGB values together.

Darken: If your selected color is lighter than the color placed on the board, your selected color will go underneath it. Because of anti-aliasing this may make your lines look rough.

Difference: Subtracts the RGB values of your selected color and the color on the board. If the values cannot be subtracted your selected color will replace the one on the board.

Hardlight: Adjusts the color of your drawing based on the darkness of your selected color. If the selected color is lighter than 50 value, the drawing is screened, which results in a lighter color. If the selected color is darker than or equal to 50 value, the colors are multiplied, which results in a darker color.

Invert: Inverts the color of your drawings.

Lighten: If your selected color is lighter than your drawing, your selected color replaces the drawing’s color. For example, you would never be able to draw on white with lighten because no color is lighter than white.

Multiply: Your selected color will darken whatever it is placed on.

Overlay: Adjusts the color of your drawing based on the darkness of your selected color. If the selected color is lighter than 50 value, the drawing and selected color are screened, which results in a lighter color. If the selected color is darker than 50 value, the colors are multiplied, which results in a darker color.
Note this is very similar but not the same as hardlight, where only the drawing is screened when selected color’s value is above 50. Otherwise they work the same.

Screen: This blend mode results in a lighter drawing, similar to add but with a more bleached effect.
Subtract: Subtracts the RBG values of the color you have selected and the color of your drawing. If value is negative, black is shown. If no subtracting can be done, there will be no effect.
