Help: Editor Tab

The Editor tab can be used to manually change the number of colors in a Mosaic. The editor can also change the color of a set of tiles in a Mosaic.

The color limiting slider in the Mosaic tab can be used to reduce the number of colors in a Mosaic. However, there are times that using this automatic color reduction technique will result in highlight colors you want in your Mosaic disappearing. The editor tab gives you complete control over how tile colors are reduced.

The Editor tab

The basics of the Editor tab

The Editor tab is divided into two parts:

Basic functions of the Editor tab

The divider between the left and right portions can be dragged to change how much screen space is used by each portion.

Resized Editor tab

In the Editor tab, the following can be done:

Merge colors of a mosaic

To merge colors, just drag the mover button to the color you want to merge it into. The editor will indicate your color merge like this:

Color merge in progress

While moving the color to merge it, the editor will show you where the color will be merged into with red arrow . Just stop dragging to complete the merge.

With iOS 11, you can use drag and drop to merge the colors &emdash; including dragging multiple colors to merge them into another color as shown below.

iOS11 multiple color merge in progress

Change the color of a set of mosaic tiles

The color of a set of tiles can be changed. Tap the color wheel button . The color of that set of tiles can be changed by moving the red, green, blue, and black/white sliders. The original and proposed colors are both shown. The Mosaic is also updated to show the proposed color.

The Revert button can be used to go back to the original color.

Tap the <Back at the upper left to use the current color.

Changing a color

When using iOS11, drag and drop can be used to copy either the original or proposed colors to another place within ColorHints Mosaic, or to another app. The example below shows dragging the original color to the proposed color instead of using the Revert button.

Using drag and drop to revert to the original color

Backing out of changes (undo)

Occasionally an edit gets made that you want back out of, or undo. Once the first edit is made, the button will appear. Simply tap it to back out of previous edits.

A long tap on the Undo button will offer to undo all changes.

Rename your Mosaic

Each Mosaic has a name. When the Mosaic is initially imported from the Mosaic tab, it is given a name that is "Untitled" and the date and time the Mosaic was imported. You can change the Mosaic name to what ever you want. There are two ways to do this. The first is to tap the Mosaic name in the detailed (right) portion of the screen.

Renaming a Mosaic

The other way to rename a Mosaic is done while managing Mosaics.

Manage your Mosaics

The Mosaic Editor supports keeping multiple Mosaics. Tap the to manage your Mosaics.

Managing Mosaics

Tapping on a entry in the list of mosaics selects that Mosaic for editing. Tap the <Back to return to the editor.

When tapped, the Import From Mosaic tab will add a copy of the what ever is in the current Mosaic tab to the Editor's list of Mosaics. (Note: this button may be abbreviated to Import or + depending on available space.)

Using a right to left slide gesture on a Mosaic will initiate deleting that Mosaic. Note that deleting the currently selected Mosaic is not permitted.

Using a long press gesture on a Mosaic entry will allow you to Copy, Delete, or Rename a Mosaic.

Copy, Delete, or Rename

A copied Mosaic will be named "Copy of " what ever the current Mosaic is named.

Tapping Delete will immediately delete the Mosaic. Deleting the current Mosaic is not permitted.

Tapping Rename allows you to edit or replace the existing name of the Mosaic.

Edit Mosaic colors using the Mosaic view

The detailed view of the Mosaic can be used to highlight colors or merge colors. These operations can be done at any time that the detailed view is visible.

At the upper right of the detailed view are a set of operation controls.


Tapping the color operator switches between the three operators.

The first, a green square indicates that selections on the detailed view will highlight all instances of the selected color. The tiles will blink a bright green color to help see tiles.

Highlighted tiles

The second color operator indicates that the first color chosen will be merged into the second color chosen. The last indicates that the second chosen color will be merged into the first color chosen. The arrow turns green when the first color is selected. If the arrow is gray, the merges are disabled (this happens when changing a color with the color picker).

As seen below, a color is being selected using a long press gesture. The first rectangle of the operator is showing the color that will be used.

Selecting a color on the Mosaic view

Selecting the second color for the merge operation is done the same way - with a long press.

Second step of merging colors from the Mosaic view

It's often useful to select the highlight operator to see all of the tiles affected. Then select one of the merge operators to perform the merge on the selected tiles. But constantly tapping the merge operator to change it can be a nuisance. To help the following short cuts are available:

Limiting which tiles are changed

Sometimes you might prefer to merge colors for just some of the tiles of a color. This is possible by using a selection rectangle to limit the area of the color merge (or color change). The selection rectangle is created by simply dragging across the Mosaic detail.

Selection rectangle to limit area of color merge or change

The changes can be limited to either inside the rectangle, or outside the rectangle. A single tap inside or outside of the rectangle changes the area to be changed. The area excluded from changes is shown dimmed.

Change only tiles outside of the selection rectangle

A double tap with one finger will enable or disable the selection rectangle

Share the mosaic

Tap (action button) at the upper left of the screen to share your mosaic.

Selecting the action button

Depending which social media networks you have accounts on, you will see a list of various options for sharing your mosaic.

Typical sharing options

Of particular interest is the EMail option. When it is selected and you have limited the number of colors in the mosaic, Color Hints Mosaic will create an annotated mosaic and send it in EMail you compose. In addition, a color key index for the annotated matrix will also be included.

EMailing an annotated mosaic

Print an annotated mosaic

Color Hints Mosaic can print an annotated version of your mosaic. When Limit is enabled, the print will include a table of colors used that looks something like this:

Printed mosaic annotation key

It will be followed by a four page version of your mosaic. Each tile has a color index printed on it. Each page looks something like this:
