I am again having trouble with filling colors in Grease pencil.
Why is it so hard to color with grease pencil.
I am only using classic materials now.
I am doing a new try.
Have you tried to increase its strength value?
Well I could not fill in the color
Grease Pencil is not my friend i guess
Yes I have set the strength value did not do anything
May you share your .blend file?
And tell what’s your Blender version?
Try not using the Gradient tool.
I did not use the gradient tool.
Oh sorry - it is the fill tool selected in the image. My error.
Hi Anton,
There are a number of things going on here, I will try my best to explain and hopefully others that know more than me can contribute as well.
The first thing I would do is wait until you have final linework to fill in color. Filling in rough linework is pretty hard to do. I traced over your character and tried my best to enclose the shapes so that they would be easier to fill. I’ll also include the blend file so you can look at it and experiment.
boy-dion2.blend (4.6 MB)
I’m not saying all of your lines need to be enclosed, that’s just the easiest method. If you want gaps in your linework you are welcome to have them but then you need a way to close those gaps. In the advanced settings there is the option to set the gap closure size (see image). You can adjust this number and see if the fill works.
You can also manually close gaps with the fill tool by holding down ALT (or Option on a Mac) and drawing a line to enclose the shape. This line can be erased later after the fill is complete. (See screenshot below)
I also noticed that you had set “Simplify” in your advanced settings to 5. I recommend reducing this number down to 1 so that the fills are nice and clean.
The last thing I want to say is that I have had fill tool difficulty in Blender versions 3.5 and 3.6. For this reason I am still using 3.4. I took the same file that I created in 3.4 and tried the fill options in 3.5 and 3.6 and the tool does not behave the same way.
(Update 7/30/23) Okay this is an issue with MacOS and Metal. If you are running Windows or Linux you should be fine. If you are on MacOS and have problems with the fill tool go to: Edit>Preferences. Click on “System.” In “GPU Backend” select OpenGL instead of Metal.
Good luck and let me know if I can help with other questions!

Many thanks for helping me out.
How can you open a 3.6 file in a lower version
3 4 looks like the developpers did not test the fill tool . The write code and create software thats all . Thanks

It depends on what the developers change when they come out with a new version. I think right now they are completely re-writing the grease pencil tool so when 4.0 comes out you won’t be able to open a current project file in an older version.
To clarify 3.4 is the version that I am able to use with ease. I fully expect that 3.5 and 3.6 work just as well, I just don’t know what settings I need to use. I recommended 3.4 just in case it’s a solution that others will find useful because they are also stuck when using the fill tool.
Good luck to you Anton! Blender is an awesome tool and totally worth investing the time to learn!
Thanks for letting me no this.
The blender method looks familiar to me. They need more artists instead of developers.
You’re welcome, Anton. I think its important to recognize all the hard work the developers have done and continue to do. They are the reason Blender exists and artists around the world can make amazing things. We owe them many thanks!
O yes but it would be wise to test with artist before they released another disappointed LTS version.
Blender 3.6 is LTS !!
well… those artists you are talking about. They are us. 
You, me, everybody. Go download the alpha build and report those pesky bugs. Helps making blender better. (Also development of the Grease Pencil module in particular was set in motion by 2D artists parallel to the regular devs if I recall correctly.)
I wiss it was true
They doing there best i guess.
