I know that.
Can you explains a bit more.
I don't really understand what you are trying to say.

I edited the post. It should be understandable now. Just rewrite this block to recognize hex 24 and 32bit correctly.
I was already Working on that.
we already talked about the naming conventions...
unfortunately you still do not follow them...
the correct name for RGBAColor would be rgbaColor
also you still have that spelling mistake in the extension name... this does not look very professional, does it?

I think you can also rename argbToHex, which would correctly indicate that the first byte is an alpha channel.
It looks like you have used appybuilder code editor. You can't rename java file there so create a new project with file name color.java and copy-paste your code there and recompile it.
I've already tried that multiple Times but IT doesn't work.
Make sure that your java file name and class name is same.
i did that but then i get this error:

Update
Update log:
The name has been changed to Colour instead of Color_Exstension and now follows the naming conventions as reqeusted by @Taifun
Also I really wan't to thank @Kumaraswamy, @Techno_Vedang and @Taifun for helping me change the name.
NOTE: the new exstension won't upgrade to the old one but wil insert a new one.
download:
com.appybuilder.lukehoogenboom.Colour.aix (7.6 KB)
great!
please edit your first post in this thread and update the screenshots
thank you
Taifun
I've updated the screenshots to the new version.
Also i've deleted the update logs to avoid confusion.
Thank you!
UPDATE
Honestly, I didn't try it out but someone might like to have the range of all colors where R, G or B is absence. It provides a nice color range, almost rainbow, about .
It goes from red -> yellow->...->red.
The number goes from 1 --> 1531
I had to analyse all thise combinations with an Excel, to transform then into a formula.
Well done!
Also:
Search here for color
to find several extensions that provide a colour picker
A bit late.
P.S. I already understood What she meant.
