I Change Colours using the Affinity Photo Colour Replacement Brush Tool

Change Colours using the Affinity Photo Colour Replacement Brush Tool


 Hi I'm Robin Whalleywelcome to lenscraft today I'm looking at how to change the color of an objectusing the affinity photo color replacement brush tool now there's lotsof ways to change or replace the color of an object in affinity photowhat makes this tool so good is that it's extremely easy to use and itcreates very convincing results to demonstrate I'll be replacing the red ofthis boat with green you'll find the color replacement brush tool groupedwith the paintbrush and the pixel tools in the tools palette if you can't seethe color replacement brush you may find one of these other tools he's showinginstead but if you click on the icon and hold your mouse button the other toolswill appear you can then click on the color replacement brush

 to select it butbefore you use the color replacement brush you should take a moment toconfigure the brush options now I'm going to start by setting the brush tohave 100% opacity 100% flow and 100% hardness this is going to make it easierfor me to work more precisely with the brush I can always modify these later ifI need to do with particular problem areas next I'll pick the replacementcolor to paint using the swatches studio panel it's also possible to make anexact color replacement if you know the RGB value or the HSL value of the coloryou want to use if you double-click on the active color you can open the colorchooser dialog where you can enter the colors to use for the replacement butfor 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 painta high tolerance means the brush replaces a wider range of colors if Iset a lower tolerance it makes the brush more precise and it replaces only colorsthat are a really near match to the area I'm painting over this is neither goodor bad you'll probably need to keep adjusting the tolerance as you paint toget the best results you'll see what I mean when we look at some of the moredifficult areas in this image having configured the brush and selected thecolor

 I want to paint with I can now paint over the red areas of the boat toreplace them with the green but before I make any changes I want to duplicate myimage layer the color replacement brush is a destructive edit and paintsdirectly onto the pixel layer replacing colors for this reason I like to paintonto a duplicate layer in case I make serious mistakes I can duplicate theimage layer by right-clicking with my mouse and selecting duplicate from thepop-up menu if I have multiple layers making of my image I'd create a newstamp layer which consolidates all the visible layers into a new layer you cancreate a stunt layer using the keyboard shortcut shift option command any

 ifyou're using a Mac if you're using a PC each shift ctrl Alt + E one of the greatfeatures of this brush is that it creates a preview as you move it overthe bolt this helps me plan the adjustments that I want to make to thebowl without actually applying them I can use this to check the color I wantto use looks the way that I think it will more importantly though I can checkthe configuration settings will correctly select and replace the red onthe bolt in each area and therefore going to check an area where I want toreplace the color first if this looks good I can click and begin to paint overthat area even though I'll try to keep close to the edge of the boat ispossible I could spill over the edge and affect other areas

 if you do find thishappening to you it's best to undo the change and makethe brushstroke again but if you don't spot the error in time you can fix itlater I'll show you how to do this later in thevideo now let's look at replacing the redreflection of the boat on the water I'll zoom into the area so you can better seeit and I can also work with a bit more precision looking at the area the redreflection presents a bit of a challenge because I want to avoid affecting thewater when I replace the red with the green if I reduce the tolerance down toaround 10% the brush will become more accurate as I paint even then however Icould still affect the water if I don't keep the center of the brush over thered what's happening is that

 The brush is sampling a color as I pass over itand then using that sample to determine which colours to replace this behavioris controlled by the sample continuously option in the toolbar when the optionsticked the color replacement brush continuous samples as you paint if I ownslightly option the brush no takes a single sample when I first click and itretains that sample for as long as I hold the mouse button down   I can now continue to replace the red inthe other areas of the boat when I come to an area which has a lot of variationin the red I can either increase tolerance or set the sampling tocontinuous by using the tolerance together with the sampling option

 I cancreate a convincing and accurate color replacement I'll just finish thepainting and then I'll show you how to clean up any mistakes   earlier I made a mistake where Iaffected the color of the water near to the boat the way that I'm going to fixthis is by adding a mass to the layer that I've been working on then I'll use a black brush to paintonto the mask in the areas where I want to hide the adjustment   if I make another mistake and revealon the boat I can fix it using either the undo command or paint on the maskwith white to reveal the green again with a little care is possible to createa very realistic color change I hope you find this video helpful there's also awritten tutorial to accompany which you'll find on

 My website I'll include alink to this in the YouTube video description I'm Robin Whalleyyou've been watching Lenscraft I'll see you next week for another video
