hi I'm Robin Whalley welcome to lenscraft today I'm looking
at how to change the color of an object using the affinity photo color
replacement brush tool now there's lots of ways to change or replace the color
of an object in affinity photo what makes this tool so good is that
it's extremely easy to use and it creates very convincing results to
demonstrate I'll be replacing the red of this boat with green you'll find the
color replacement brush tool grouped with the paintbrush and the pixel tools
in the tools palette if you can't see the color replacement brush you may find
one of these other tools he's showing instead but if you click on the icon and
hold your mouse button the other tools will appear you can then click on the
color replacement brush to select it but before you use the color replacement
brush you should take a moment to configure the brush options now I'm
going to start by setting the brush to have 100% opacity 100% flow and 100%
hardness this is going to make it easier for me to work more precisely with the
brush I can always modify these later if I need to do with particular problem
areas next I'll pick the replacement color to paint using the swatches studio
panel it's also possible to make an exact color replacement if you know the
RGB value or the HSL value of the color you want to use if you double-click on
the active color you can open the color chooser dialog where you can enter the
colors to use for the replacement but for this example I'm just going to use
one of the colors in the color swatch
next I'll set my tolerance to around 30% the tolerance controls how wide a color
range the brush replaces when you paint a high tolerance means the brush
replaces a wider range of colors if I set a lower tolerance it makes the brush
more precise and it replaces only colors that are a really near match to the area
I'm painting over this is neither good or bad you'll probably need to keep
adjusting the tolerance as you paint to get the best results you'll see what I
mean when we look at some of the more difficult areas in this image having
configured the brush and selected the color I want to paint with I can now
paint over the red areas of the boat to replace them with the green but before I
make any changes I want to duplicate my image layer the color replacement brush
is a destructive edit and paints directly onto the pixel layer replacing
colors for this reason I like to paint onto a duplicate layer in case I make
serious mistakes I can duplicate the image layer by right-clicking with my
mouse and selecting duplicate from the pop-up menu if I have multiple layers
making of my image I'd create a new stamp layer which consolidates all the
visible layers into a new layer you can create a stunt layer using the keyboard
shortcut shift option command any if you're using a Mac if you're using a PC
each shift ctrl Alt + E one of the great features of this brush is that it
creates a preview as you move it over the bolt this helps me plan the
adjustments that I want to make to the bowl without actually applying them I
can use this to check the color I want to use looks the way that I think it
will more importantly though I can check the configuration settings will
correctly select and replace the red on the bolt in each area and therefore
going to check an area where I want to replace the color first if this looks
good I can click and begin to paint over that area even though I'll try to keep
close to the edge of the boat is possible I could spill over the edge and
affect other areas if you do find this happening to you
it's best to undo the change and make the brushstroke again but if you don't
spot the error in time you can fix it later
I'll show you how to do this later in the video
now let's look at replacing the red reflection of the boat on the water I'll
zoom into the area so you can better see it and I can also work with a bit more
precision looking at the area the red reflection presents a bit of a challenge
because I want to avoid affecting the water when I replace the red with the
green if I reduce the tolerance down to around 10% the brush will become more
accurate as I paint even then however I could still affect the water if I don't
keep the center of the brush over the red what's happening is that the brush
is sampling a color as I pass over it and then using that sample to determine
which colours to replace this behavior is controlled by the sample continuously
option in the toolbar when the options ticked the color replacement brush
continuous samples as you paint if I own slightly option the brush no takes a
single sample when I first click and it retains that sample for as long as I
hold the mouse button down
I can now continue to replace the red in the other areas of the boat when I come
to an area which has a lot of variation in the red I can either increase
tolerance or set the sampling to continuous by using the tolerance
together with the sampling option I can create a convincing and accurate color
replacement I'll just finish the painting and then I'll show you how to
clean up any mistakes
earlier I made a mistake where I affected the color of the water near to
the boat the way that I'm going to fix this is by adding a mass to the layer
that I've been working on
then I'll use a black brush to paint onto the mask in the areas where I want
to hide the adjustment
if I make another mistake and reveal on the boat I can fix it using either
the undo command or paint on the mask with white to reveal the green again
with a little care is possible to create a very realistic color change I hope you
find this video helpful there's also a written tutorial to accompany which
you'll find on my website I'll include a link to this in the YouTube video
