Thanks a milltion for your answer. It is always a great pleasure to have a
contact with responsive developers.
While the link you provided is certainly most useful a problem does remain:
the colours are always washed-out. This is almost certainly a problem of
MacOS but still quite annoying. What I do in Iconstix is to prepare a
coloured folder and use it as input for a second coloration. Then the
colours become really vibrant. Unfortunately I cannot figure out a way to
do this in Image2icon. I guess that I'll have to live with two different
apps for slightly different tasks.
I think the washed out is 50/50 macOS and our problem. The standard folder icon have little details on it which make it almost impossible to produce the same icon in different colors without having the original image layers ( think about it as a photoshop file ).
I have to study how Iconstix solved the problem but I suspect they are using their own version of the folder, which is a clever way to handle the problem but in our experience Image2icon are really fond of having the "real" folder ( which is also slightly different for each MacOS version).
I am afraid that the problem of washed out colours is 100 % MacOS. The way Iconstix solves the problem is by allowing to pile up many icons. Thus one prepares a folder with washed out colours, inputs it and then recolours it. Image2icon cannot do this since there is a built in restriction of adding just one icon to a template.
I agree with you that having the "real" folder, which evolves with the MacOS version is great. The only thing I do not like is the light-blue colour.
Many thanks for taking your time to address my questions
I have been experimenting with colouring the folders and I think that i have found a solution which does not necessitate custom templates. It suffices to provide a folder of the same form as the system one but of white colour. When one colours the background the colours are what one expects and not washed out ones. I tried this on the iOS icon which is white and it works.
And if you work on the system folder icon it wouldn't be bad to provide icons corresponding older systems. The current one is too "square" to my taste but of course this is just my opinion.
you'll loose the folder textures and possibly some shadows, which is one of the coolest details of the icon itself ( in my opinion ). I think we can provide a white flat option folders icon template but will have to the sole purpose of being colored and I don't know if this will "fit" in image2icon.
Image2icon use different folder icons for MacOS 10.9, 10.10, 10.11 and 10.12 but they are not choosable, it automatically switches base icon when the OS version is detected. Usually, no one wants the older icons but I get your taste :)
