Are there constants for colors?

I noticed that you have to use hex code for text color. I don't know hex well enough to shoot from the hip. Is there another way to select a color, like constants (or maybe even RGB code)?

Well, technically hex is also RGB, but I get what you mean.

You can use some online converting tool to get hex value http://www.javascripter.net/faq/rgbtohex.htm

of use some conversion functions http://gameon365.net/topic/1886-lua-convert-rgb-colors-to-hex/

but usually, all design programs, like photoshop, paint.net, etc can already output the color in any desired format, including hex.

I don't know of any, but there are a ton of online tools you can use.

Here's a page with a color chart:

And here's a color picker which shows you the hex code at the top:

I'm sure there are many others - I googled "hexadecimal color" to find those.

You can do this...

function rgbToColor(r, g, b)   local sum = r * 65536 + g * 256 + b   return sum   end   application:setBackgroundColor(rgbToColor(123, 321, 124))

Alternatively you can also use this free mac utility (SIP)to pick colors from screen/images and convert to the format that you want (copied to your clipboard)

It provides easy navigation between color models, color history...
I found it to be useful in my workflow.
