What is the Colorization Mask?

The strokes that you draw in order to add, protect or remove colors from the photo arease are also referred to as Masks. There are color, gradient, protection and decoloring masks.

Masks appear in two modes: 
(a) Normal Mask 
(b) Transparent Overlay Mask.

When you save you work to CODIJY Document, the masks get saved along. You can export and import masks in the Pro Edition of CODIJY.

Rules of drawing masks

  • Draw masks close to the border without stepping over it.
  • CODIJY automatically detects borders between objects, once you provide colors for all neighbouring areas. 

Color masks

You can draw color masks with the Pen Tool (P). You can pick colors for color masks from extensive collection of Color Libraries or using Color Picker

Gradient Masks

Gradient masks let you add multiple colors and their transitions with a single stroke.  Gradients can be helpful when you colorize faces and landscape features.

Enable the Gradient Pen (G) tool to add the gradient mask.

TIP: When you draw the gradient mask, try to draw the stroke over the areas you wish to apply the colors of the gradinet to. If you captured the gradient, follow the route you took in the Gradient Capture Tool and draw the mask over the same area.  

Option 1. Pick the Gradient from the Color Libraries (Pro Version)
Option 2 Compose and edit in Gradients Settings Dialog 
Option 3 Capture a Gradient from a color images using Gradient Capture Tool (Pro version)

Color Protection Masks

To protect original colors of the area, use protation masks. Draw the protection masks with the Color Protect Pen (X).

TIP: We recommend covering the whole area with the protection masks for the quality protection result. Increase the brush size of the Protection pen, to speed up the drawing of such mask!

Decoloring Masks

Use De-color pen (D) to draw the decoloring masks when you want to convert or leave some areas to the grayscale.

TIP: Decoloring masks are generally useful with e.g. white clothes, silver or iron parts.

Export/Import Masks

You can export the Masks to the CMSK files and import them for another image using the related toolbar icons or navigating to the related command in the File menu. NOTE: This feature is available in Pro edition only.

TIP: Export/import saves time when you colorize similar images e.g. movie screens.

Drawing Tools


CODIJY drawing toolbox includes four pens: Pen tool, Gradient Pen, Color Protect Pen and Decolor Pen. You can access them from the Tools toolbar or under the Tools menu.

Pen tool

The Pen Tool lets you draw color masks. You can pick colors from the Color Picker, Color Libraries, from color & gradient masks as well as entire images using the Color Picker tool. Colors are saved to the Color History.

You can enable the Pen Tool using the toolbar icon or (P) shortcut

Gradient Pen

Gradient Pen lets apply multiple colors and their transitions with a single stroke. Gradients can be helpful when you colorize faces and landscape features. You can:

Option 1. Pick the Gradient from the Color Libraries (Pro Version)
Option 2 Compose and edit in Gradients Settings Dialog 
Option 3 Capture a Gradient from a color images using Gradient Capture Tool (Pro version)

You can enable Gradient Pen by clicking its icon on the tools toolbar or using (G) shortcut.

Color Protect Pen

This tool protects original colors of the area, while image processing. You can switch to Color Protect Pen using the below icon or (X) shortcut

Tip: Color protection is often used, when you want to protect black and white colors, metals, white shirts, when colorizing black and white images. It’s also needed, when you decided to recolor an object or two on the color photos.

Decolor tool

Decolor pen is used to convert objects and areas to black and white. Even, if your work on an old vintage image, its color scheme may not be in pure grayscale. Some photos turn yellow or brown, thus making objects like metal, white clothes, teeth look pale. Decolor pen lets you get rid from all pale tones.

You can switch to Decolor Pen using the icon or D shortcut


The standard Eraser tool lets remove color masks. You can switch to Eraser using the icon or (E) shortcut.

Pen Settings

You can change the brush size and mask mode of all four Pens and the Eraser.

Brush Size

The Brush Size is accessible from the standalone toolbar. Depending on its position. Please note that ir will look divverently in the vertical and horizontal positions.

It’s also available via the Context menu that pops up over the masks when you have any of the four Pens or the Eraser enabled.

You can change the line width by changing the value or adjusting with s scroller. Also you can press “[“ for decreasing brush size and “]” for increasing it.

Line Style

There are two line styles: the straight and freehand lines. You can switch between them using the corresponding toolbar buttons.

Alternatively, press “F” for freehand and “L” for drawing in straight strokes. Use “Space bar” to cut out the line strokes.

Drawing Line masks without releasing the mouse button

You can complete this mask without releasing the mouse button (or raising the pen) with the help of two shortcuts!

  • Press Spacebar to cut off the line and change direction.
  • Press and hold Spacebar to switch to Freehand drawing

Image colorization

CODIJY allows you to add, remove and protect photo colors, by drawing simple Masks over photo areas using several Pens.

Add Color masks

NOTE: This is a concise description of colorization process. Please check out our CODIJY Lessons for step by step colorization tutorial.

Most of colorization is done with solid colors. Use Pen Tool to draw color strokes (masks) over different photo areas.  Pick colors from Color Libraries or using Color Picker

CODIJY automatically detects borders between objects, once you provide colors for all neighbouring areas. 

TIP: The example file of this coloriztaion with related Color History and masks is packed with CODIJY and can be accessed from the Project Explorer.  

Enable Pen Tool (P).  Start with ready colors. Select a Color Library from the drop down list. 

Pick a color and draw the mask within the area, close to the border. By default, you will be drawing in Freehand Mode (F).  

If the area has a regular shape, switch to the Line Drawing (L). Line masks are quicker to draw. 

NOTE: Use several shortcuts to draw masks in the Line mode quicker.

  • Spacebar will cut off lines in Line mode,
  • Escape button will delete the previous line, when you hold the mouse button down.
  • Long-press Spacebar to switch to the Freehand mode, without releasing the mouse button.   

To change brush size, use Brush Size tool on the toolbar or call the Context Menu over the Mask.   

You can access previously used colors from the HistoryNOTE: you can enable History, if it was disabled in your layout. 

Generate result preview

Process the image (press Ctrl + R (Win) / Cmd + R (Mac)) or click , when you are done or want to preview the colorized result. 

Quickly edit the mask color

If you want to change the mask color on the spot, adjust it Hue / Saturation / Brightness using the HSB Repaint tool

Step1. Enable HSB Repaint Tool by pressing (H) or clicking on the toolbar.

Step 2. Click the mask. The HSB dialog will pop up. 

Step 3. Adjust Hue/Saturation/Brightness parameters using handles or the digital values. The Mask color will change in the real time. Process the image (Ctrl+R / Command+R) to preview the Result. 

Alternatively, use the Color Picker tool and Repaint Busket.   

How to draw Gradient masks

Gradient masks let you add multiple colors and their transitions with a single stroke. 

To draw a gradient mask: 

Step 1. Select Gradient Pen tool on toolbar. 
Step 2. Use ready gradient from the Color Libraries or capture on from a color photo.

NOTE:  We are using the gradient saved to the Color History of the example file packed with CODIJY. You can find it among examples in your Project Explorer

Step 3. Draw the gradient mask trying to match colors of the gradients to the areas that you mean them to applied to. 

Step 4.  Click Apply Gradient in Gradient Settings or simply press (B) after the mask is completed. NOTE: If you don’t apply the current gradient, the newly selected gradient will apply to the last drawn mask.    

Process the image ( Ctrl + R (Win) / Cmd + R (Mac)) to generate colorized Preview.
