Select similar colours


Recommended Posts

Hi,

in Photoshop there is a function, in german called "ähnliches auswählen". In english it's called "Similar" in selection-menu. The function automatically  select a similar color. So for example if I select a area with red color and I run "Similar", photoshop selects all areas with a similar red color.

How can I do that with affinity photo? Is there a similar function?

Thanks for any hints,

Hi chapolote,

Welcome to Affinity Forums :)

No, currently there's no similar function in Affinity Photo. If you are selecting the colour on a single layer you can try to use the Flood Select Tool, set the Tolerance as you see fit to pick just the colour you want, untick the Contiguous checkbox and It should select the same colour from the whole layer.

hello everyone!

 

Is there any update maybe with selecting similar/same colours in Affinity Photo?

"Flood Select Tool_set Tolerance_untick the Contiguous checkbox" is a good trick, thank you! , but not precise enough. 

Here we exported Material ID photo where all colours are different, but is not possible to select them fully. With low tolerance (if we check the selected green grass) not whole colour is selected, but with just a bit higher tolerancy, there is another green colour selected together. 

 

Any tips on how to fully select colours on Material ID photo? :)

higher tolerance:

Besides flood selection tool, we have select sampled color.

https://affinity.help/photo2/en-US.lproj/pages/Selections/selections_sampled.html

in your case it might be best to combine multiple selection methods:

  1. first sample by color
  2. the set mode to subtract or intersect and use rectangle or lasse to remove unwanted areas

other Tipps:

  • use RGB/16 instead of RGB/8
  • check „continuous“ and add all areas sequentially,
  • Select „too much“ first with large tolerance value, then subtract unwanted colors after reducing tolerance
  • create a temporary „merge visible“ layer used only to create selections
  • try live hue mask, live luminosity masks, and compound masks.
  • if you are able to exactly specify the RGB color ranges, i can provide a procedural texture filter creating a view which can be converted to mask or selection.

in your image, some green tones in the building windows / frame edges are identical to those of the plants. So no chance to select only by color.
