Tell me, please, why does the intersect delete, but not cross path, and the subtract does not subtract, but intersect path? Why're they doing the opposite?

This is the picture

And this is what it looks like in my Gimp, because the screen is too small. How to enlarge the screen?

* when i paste something, the float layer starts off locked by default
* i know how to manually click the un~lock icon to un~lock it
? but, is it possible to have float layers be un~locked by default

I have an avatar sheet like the attached sample and was wondering if Gimp has some kind of automated tool or if there's some sort of "trick" to cut them out altogether instead of one by one.
I need each avatar in 100x100.

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?
