Precision: 8, 16 or 32 bit? |

Hi,
I was trying to use the RGB equivalent of a specific CMYK, namely 4,100,95,0 (RGB = 244,8 0,0 12,8; #F5000d).
However, although I selected this color (# F5000d) the result when checked was always #F5000c; RGB 245.0 0.0 12.0
Even at http://paletton.com/#uid=75B0u0kw0vijNCzp8xHytouDMjd when I entered the code #F5000d, the code #F5000c was automatically assumed.
I struggled with this limitation for some time until I finally looked for a solution.
This happened by chance, when doing experiments I changed the precision from 8 bit to 16-bit integer and voilà.
With that precision, I was able to select the color #F5000d and now the Color Picker Tool recognized that color. (Although the RGB slightly different 245.0 0.0 13.0)
I am not aware of this precision issue (Image - Precision - x bit)
Does choosing between 8 bit, 16 or 32 results in some type of higher memory or processor consumption?
Can I select the option 32 bit (or 16 bit) without any fear of any unknown consequences?
In general what reference should I take to find out what is the best precision that best suits my use?
Thanks in advance!

Where are 2.10 thumbnails? |

Hello everybody,
I recently switched from 2.8 to 2.10 (Windows 8.1). Everything works just fine but :
- In 2.8, all the thumbnails generated by GIMP were stored in C:/Users/MyName/.thumbnails/normal
I used to manually get rid of the many useless thumbnails from time to time.
- But in 2.10.18, the thumbnails seem to be stored somewhere else, and I can't find where.
Can anybody help me ?
Thanks in advance.

I like Inkscape grid colours. They look very clean and crisp. When I tired GIMP the grid colours were as if it had a tone of sepia to it.
It will great if anyone can teach me how to make GIMP grid as in Inkscape. Thanks.

Retain RGB values on 0 alpha pixels? |

I am making a Minecraft texture pack for bedrock edition, and the grass overlay system puts the overlay color on top of the RGB value of a given pixel, with the transparency of that pixels alpha channel. What this means is, to make a proper texture, you need to put the dirt part of the grass with an alpha of 0.
Unfortunately GIMP replaces the RGB values of a 0 alpha pixel with black.
Does anyone have a way to make a completely transparent pixel that still has a chosen RGB value?

Hi. Trying to change the color of the bucket fill function in python gimp, but due to my inexperience with python and the structure between gimp and python i have not been successful.
Information im looking for is:
How to swap the pre-selected colors
How to set new color
How to fill and selected area
How to select and area
All of which needs to take place in pyGimp
The bellow code is what i have so far, but the result is what i expect.
Expected result should be an grid (almost like a chess board) where pyGimp color individual squares in one of the two colors (foreground and background)
#Select and square
pdb.gimp_rect_select(img, gPosX+pX, gPosY+pY, wid, hig, CHANNEL_OP_REPLACE, False, 0.0)
#Fill the square
draw.fill(FILL_FOREGROUND)

Any idea on how to make a color wheel in gimp?
Just a simple pie visual, except instead of for the purpose of percentages it's just to show the rainbow +3 other colors (white, brown, and black) so 9 colors in all
