[Free] Color Extension

[Patryk_F]

I think you can also rename argbToHex, which would correctly indicate that the first byte is an alpha channel.

@Sketch

when I change the name the exstension breaks

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.

[Sketch]

I've already tried that multiple Times but IT doesn't work.

[Techno_Vedang]

Make sure that your java file name and class name is same.

[Sketch]

i did that but then i get this error:

The file name should not be the same as imports or object names.

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.

@Sketch

great!
please edit your first post in this thread and update the screenshots
thank you

Taifun

[Sketch]

I've updated the screenshots to the new version.
Also i've deleted the update logs to avoid confusion.

[RR_Media]

Nice extension @Sketch!

[Sketch]

Thank you!

[Roeland]

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.

[TIMAI2]

Well done!

Also:

Search here for color to find several extensions that provide a colour picker

[qwe_rfv]

I think @Anke is trying to say that he/she changed another extension name without any problems

[Sketch]

A bit late.
P.S. I already understood What she meant.
