Sometimes the color swashes in the Toolbox have purple corners:

   

• in color-indexed images for any color which is not in the color map
  
• in greyscale images, for any color which is not neutral gray
  
• in RGB images, when the color is picked in a non-RGB color model (HSL, for instance) and has no corresponding RGB equivalent. In this case, the color selector uses the same purple color(*) in the selector widgets to indicate the out-of-gamut ranges.
  

Isolate colors by using the Mono Mixer :
- load picture
- copy layer
- set new layer active
- set new layer mode 'Luma lighten only'
- on menu : Colours / Desaturate / Mono Mixer
- tick 'Preserve luminosity' on
- play with the red, green and blue channel multiplier sliders 

   
   
   
   

A script that emulate the David Hill effect on images can be found on (tested on windows 10 / gimp 2.10.14):

Hi, all.

I've been searching and clicking around and not finding what I'm looking for.  I want to change the color of the path I'm editing.  Not the stroke color, the actual path's color.  It's always red.  I'm trying to trace a source bitmap that has a lot of red lines, so I'd like my path to be some other color, in order to more easily differentiate between the source and path I'm creating.

Is there any way to do this?

2.10.14 on Windows 10.

Thanks.

Can anyone give me information about the two colors in the color selection dialog box. If I load the original picture with the green there is no problem. When I start a new picture (here white BG) and want to work with the green color the result on my drawing is grey. I searched on the internet but found nothing about this. 
Thanks for the answer in advance.

     

Problem solved, I don't know how but I was working in grayscale mode and it must be RGB   :

Image / Mode / RGB

I am trying to make my text follow a path I've created. I'm in the text layer and have a path created. When I right click on the text, Text to Path, is not highlighted. Why?

Hi I post it here because I can't post in gimp 2.10
I'm a newbie.
I open a new project
I draw a circle in it.
I fill this with a pattern ,everything ok.
Now I open a picture of let say a cross(downloaded from the internet.
I fill with a pattern but the filling is now black and white.
What do I wrong?

Kind regards

When I try to draw a selection box on the image it says "Cannot subtract from an empty selection."
Why is that and how do I make it stop?

Hi

Loaded a tiff image whose original size was 3914 x 5871 pixels (portrait mode). It appears in Gimp as a tiny image 168 × 252 pixels! When I try to scale it it loses quality which I cannot recover through any of the interpolation quality options. I must be doing something wrong when I load it! Any suggestions gratefully received!

It is possible to render the available fonts in Gimp to a file as a 'preview' or permanent record.

(1) Right click in the Fonts dock and select Render Fonts Map
(2) The default is a list of 'Sans' Type fonts
(3) One per layer in the image

   

(4) Leave the filter blank for all the Gimp fonts. Expect a very long listing
(5) ..or a specific style, bold / italic....
(6) A specific font, your text / font size / colour
