I contacted the author of Just Color Picker at annystudio.com about this issue, and he/she (I presume Anny would be rather she) replied that they are aware of it because a few users already notified them in the past. I was surprised that Anny hasn't done anything about it, but that's their choice. I personally wouldn't be so forgiving.

Anny actually advised me not to worry and rather just use the software I like the best. The author has amazingly kind and soft attitude and said that it is not the first time their software and other work has been copied, but instead of taking actions they merely see it as a compliment: it is copied because it is truly good! Anny said that instead of wasting time chasing small wrongdoing, they prefer using this time and energy on creative work.

I see the point here: nobody would copy rubbish, but I would definitely be furious if someone was stealing from me like that. I am already furious because someone stole from them!

But.... the wish of the author is the law here, so I'm going to follow Anny's advice to use the software I liked and leave this case of petty theft at that.

I was looking for a color picker for my web design project, and tried heaps of them today. I saw this discussion, and couldn't walk past. I think the earlier versions of Color Man were indeed a copy of Just Color Picker's interface. The fact that the authors of Color Man added more color formats doesn't conceal the fact of the interface plagiarism. It is like adding one page to a stolen poem doesn't make it original. The newer version of Color Man's interface seems to be slightly reworked to make it different to JCPicker .

By the way, ACA Color picker IS a copy of Just Coor Picker too, they even copied the description from JCPicker's page and forgot to edit the name of the original program! So, comparing Color Man to ACA only makes things worse.

But all those plagiarism accusations aside, I did choose Just Color Picker in the end, because the quality of its make is by far superior to anything else I tried.

If - and only if - we say that Capture Color Man a is a copy, then Color Archiver (free) and Aca Color Picker (cost : 19,95 $ !) are copies too, because
they are many much similar to JCP than Capture Color Man.

Capture Color Man had big differences than JCP. It's obvious. There are
similarities too, but do not forget it's because all of these sofwares are made
for color capture.

So, I don't understand the discussion in the previous posts. It's a shame to
tear down a free software for unjustified reasons! I give a break to Mr Azar, Mr Simon Goldbaum is right, Capture Color man is not a copy.

Anyone who use Capture Color Man can see that the interface is really different than JCP. Just have eyes to see...

Mr Simon Goldbaum thinks that if the developers totally copy a unique interface of another program and then just add one more function to it, it becomes "not a copy". Give me a break!
I've been using all versions of JCP for many years, and know how it's author has been perfecting the interface from version to version.
By the way, JCP is free too.
