Editing colors in Step 3 is similar to modifying mosaic pieces. When
mosaic piece is too big, it can be split into multiple ones. When two
pieces need to be joined together, they are merged. Different images
require a different amount and type of editing.
To split an area, select Split after clicking on Edit Colors in the
Step 3 toolbar
and click on the area. It will be split into two or more areas.
The two pictures below show the image before and after splitting an
area (outlines are not shown). In this example the original area covers
a portion of the head and a portion of the background.
Any resulting area can be split again.
The Edit Colors toolbar has three radio buttons for four modes: Split,
Merge, Despeckle and Replace Color. To change the mode, select the
corresponding radio button. After the mode is selected, click on the
area to be changed.
To merge two areas together, select Merge in the toolbar
and click on
the first area; it's border will be highlighted by a blue outline as
Next, click on the second area, the two areas will be merged into
one and this larger area will become highlighted.
Click on the additional areas (if any) to be merged with the
currently highlighted area. In the example below four parts of the
green background are all merged
and so their shade becomes the same.
The merging areas do not have to be connected. If areas that are not
connected are merged, their colors become the same.
When making a portrait, it may be useful to merge two eyes so that
their color becomes the same.
Summarizing, in the Merge mode, the first click selects the first
merging area and the second click selects the second one and actually
does the merge. A click on the third area adds this area to the first
two. To select a different first merging area, right-click
on that area. Very small areas are hard to click on. They can be merged
with the surrounding large area by selecting the Despeckle mode and
clicking on the large area.
When two areas are merged, the color of the new area is the average of
the two colors. So during Split, Merge and Despeckle operations the
colors of the areas are always changing. It is possible to change the
color of an area to any desired color. Select Replace Color in the
click on the area and choose a new color from the saved custom
colors or the color palette.
Replace Color mode can also be used to save the current color of an
area for further use. Check the Replace Color option and click on the
area. In the pop-up color menu, click Add to Custom Colors and then
click OK. Up to 15 colors can be saved this way.
It makes sense to replace colors after the splitting and merging of
image (or of a part of the image) is done because if a re-colored area
is split or merged, its color is changed to the original one. Also
merging is often best done after splitting.
Any operation of the Edit Colors set can be undone (and redone)
the Undo and Redo buttons. The image can be zoomed in with the Zoom In
