Take also a look at and the https://en.wikipedia.org/wiki/Color_space conversion of color spaces, the mapping of one color from one space into a color of another space. Wider color spaces as sRGB (like Adobe RGB, ProPhoto/ROMM) do have and offer colors you can't directly/exactly map 1:1 into lower color spaces, since the lower color space might not contain that color at all. Thus also look at the different gamut sizes (color space sizes) shown there in the above link. - BTW, ProPhoto RGB and ROMM RGB are (or should) be nearly the same, since it's usually just another name for the same child. Also if you initially create the images in Adobe Animate, what color space do you use there (sRGB ?) and do you embbed the used profile from there into your exported PNG images or not? Meaning do you save the PNG with an reusable embedded color profile or not?

Don't know if your Mac version of MS Word offers the same here (linking in, instead of embedding images), but if a document is to be printed (commercial or high quality), another approach is to Link to the images rather than embedding them. That keeps the document file size at an absolute minimum, but the image files need to accompany the document in order to render optimum quality when printed.

Yes as @>|< already said, don't mix up document and printer (display input and printing output) color profiles here. I think you should first get some better knowlege and understanding about the color management materia, before you go to dive in and try out things. See for example: Tutorial on Color Models, Color Spaces and Color Profiles (two-part) What are Color Models? What are Color Spaces, Color Profiles and Gamma Correction? Make yourself clear that the document profile is meant for display purposes, aka monitor based devices which show images on screen. Here the defacto smallest common denominator is the sRGB color spectrum, which can be said to be the default or standard one. In contrast to sRGB, Adobe RGB or ProPhoto are much wider color gamuts (color space) which do offer much more colors in their respective spectrum. - The Canon PRO-100 is instead a printer profile (an output profile in CMYK color space) which will be Canon vendor calibrated for your specific Canon printer for output. So you would supply this one only on print panels for paper printing output, but not for displaying a document on a monitor. Usually your printer driver associates the right printer profile with the selected printer for the output here. So be careful you do not confuse anything essentiell and unnecessarily waste ink and paper here!

Don't know which App and OS is meant here, so I assume Designer here, additionally to what @walt.farrell said take a look here ... Selecting, Finding and Isolating Objects

Just remembered U.F.O. for falling stars!

Well create a 800 x 800 px doc, place a 5 point star on that, select the star (see it's bounding box) and enter into the transform panel x = 0 px, y = 0 px, w = 800 px, h = 800 px, what do you see for the star and it's bounding box? "Catch a falling star, put it in your pocket ..." (Prince Kajuku).

You will need closed paths/curves for vectors in order to fill those, see how @dutchshader did it by reusing symbols here. He already made an kaleidoscope AD example file. EDIT How it looks when I apply instead your above moire pattern to what @dutchshader showed above. I used the style file I've posted before for filling his symbols here...

For that working with vectors (using Designer) instead of an bitmap for the kaleidoscope image would be better. So if you recreate the kaleidoscope image as a vector drawing with objects and curves in Affinity Designer (tracing as vectors with a tool, or retrace by hand) you can then fill the objects with your different PNG moire patterns bitmaps via styles. As I've shown in the first posting above. - That should offer a greater flexibility and reusability for later tweaks and the like.

You can try out the remove dust filter together with some levels adjustments in order to remove or milder that white area.

There are probably many ways which leed to Rome, but for Affinity Photo once you have the selection, you can use the gradient tool and load with that a bitmap of your moire (your moire PNG file) and place and adjust the moire contents as a fill and size it accordingly to your needs.

See for example: Affinity Photo Tutorial #25-Flood Selection Tool

This might depend on the sources you got the initial version from. For example as for Mac App Store versions the Apple store indicates and tells you that there are updated versions to download. - Other than that usually you also get infos related to this via Email from Serif, as far as you are registered on their web site. And the forum here will also tell if there are newer versions available. In order to check you have to take a look at your "Info ..." panel shown version number and compare with the latest announcements. I believe that newer and upcoming application versions will have a build-in update mechanism in future, which will tell you then automatically that there is a newer version or update for download available!

You can even make a Touchscreen-Mac out of the Mac mini with the help of an iPad and some third party tools (Luna Display).
