What is this this color code " rgba 100,100,100,.5"?

Can you please tell me what is this "rgba 100,100,100,.5" color hexadecimal code? I like to use it for my blog post text color. If you know it please help me.

Thanks!

 

its #646464

 

You can use it so too
For example
h1 {
color: rgba(100, 100, 100, 5);
}

Pay attention to the "A" part of RGBA -- it's not simply #646464, as it's also 50% transparent.

The first three digits are red, green and blue in a range 0..255 (00 to FF hex)... that fourth number is transparency ranging from 0 to 1 as a floating point number. You set that fourth number to 0, it's 100% transparent. You set it to one, it will be #646464 -- at 0.5 it is blended 50% with whatever it's being drawn over.

 

Thanks you friends your replies. Yes looks like that's the color, but looks like its brightness lower than the font that I saw. How do i increase that color code brightness.

I like to use this site post color, I think it also similar to this color, but it more thicker. http://www.macgasm.net/2012/12/29/apple-agrees-to-drop-patent-claims-against-samsungs-new-phone/

Thanks!

 

Oops, should say first three numbers, not digits when using rgba.

rgba( red 0..255, green 0..255, blue 0..255, alpha 0..1)

#333333 -- darker
#888888 -- brighter
#999999 -- even brighter
#AAAAAA -- far brighter
#FFFFFF -- white

When red, green and blue are the same, you get greytones... so just make each pairing higher/lower. You can also state them as 3 digits long.

#333 == #333333
#888 == #888888
#FFF == #FFFFFF

You lose accuracy, but save a few bytes.

Oh, and are you at least familiar with hexadecimal numbering? Each digit is a factor of 16, not ten... 0..9 still represent 0..9, but A..F represent 10..15. As such FF == 16*15+15 == 255.

Or in the case of the original rgba(100,100,100,0.5) each of those 100's ends up being 64 hex.
6*16+4 == 100

 

Thank you friend your detail answer. Yes it help very much.

 

First time I have seen the color code like that ,
I am confused for .5.

 

Final number is alpha -- aka transparency. 1 would be 100% opaque, 0 would be 100% transparent, so 0.5 is half transparent/half opaque (depending on if you are a pessimist or an optimist)

 

#646464 you can use this one.
