24. Add Color to the Analog Image using Multiply

It is good training to trace line drawings, but if you want to take a shortcut and just apply color, or if you want to apply color to someone else’s line drawing you can use the Multiply blend mode.

First, open the ①Layer window, tap ②Import from Photo Library and then select an image. Images with white parts that are very white are easier to work with and produce better results. After loading the image, it might be a good idea to adjust the “Brightness & Contrast” from the filters in the FX button.

Next, place the image using a ①one finger drag, and then set the size you want using ②two fingers (pinch) to zoom in and out. Finally, tap the ③End button.

Drag the transparent ①Thumbnail (small image) above the image and then tap it to make it the Current Layer.

Tap part of the Layer window which reads ①Normal and change it to ②Multiply from the list. This will change the Current Layer (the transparent layer) to Multiply mode.

Applying color to a Multiply layer creates a color which is made from the multiplication of the applied color and the color on the layer beneath it. If the lower color is black then the result will be black (as black is defined as 0, and 0 multiplied by 0 is 0). If the lower color is white then the color will not change (as white is defined as 1, and anything multiplied by 1 remains the same). In ibisPaint colors are given a number from 0-1 depending on their brightness. Multiplying a number by a number between 0 and 1 will produce a result which is either the same number or less than that number. This means that the result will be the same color or a darker color.
Simply put, the Multiply layer will be the brush color where the layer underneath is white and black where it is black.

Since a solid block of color is not very interesting, a new layer has been added above, clipping has been applied, and opacity has been lowered to 20%. Selecting Marker from the Brush Tool, we can add a bit of duality to our image creating something unique. To finish from the Filter menu the "Wet Edge" has been selected to give the impression of a watercolor image.

The finished example looks like a hand drawn sketch that has been colored in. Doing it this way makes for a different feel to an all digital artwork.
