## What is RGB checker?

This tool is very simple and useful for checking colors! Especially, good for HTML developers, illustrators and graphic designers.
Also I use this tool myself, so I recommend for mobile app developers as well.

*** Features ***
- Displays RGB values/colors to decimal numbers and hex numbers!
- Easy & quick checking any colors!
- Editor for text and background colors!
- Multitasking(for iPad)

*** Color Info ***
- 240 Web-safe colors.
- 140 X11 colors.
- Basic 16 colors.

*** How to use it ***
In editor tab, text/background color can be changed using RGB sliders. Also you can edit the text.

*** Tips ***
In other color tabs, you can pinch zoom.
Also if you double tap any color, it will be shown the color with whole screen.

I hope this app helps you!
