I have this code for a color,0x7FBB00FF I don't know how are called this colors with 0x and where I can found a convert for photoshop ?
It's RGBA: hexadecimal with an alpha value at the end - FF.
Type the relevant bit of the color code into Google to see it as a hex color (#7FBB00): https://www.google.com/search?q=%237FBB00
Hexadecimal.
For #0x = See that post
7F = Red
BB = Green
00 = Blue
FF = Alpha
That comes from google:
It could be a Android color
or Q-Image Format
How to easy convert per Hand
The 0x prefix usually means hexadecimal.
And each color channel usually uses 1 byte, that is, it ranges between 00 and FF. That's 2 digits in hexadecimal.
The convention order is red (R), green (G), blue (B).
Sometimes an alpha (A) component with the transparency is also added.
So your color is probably in RRGGBBAA.
Red: 127
Green: 187
Blue: 0
Alpha: 255
In CSS, you would use
rgba(127, 187, 0, 255)
Or, since FF usually means fully opaque, you don't need the alpha channel.
rgb(127, 187, 0)
#7FBB00
But sometimes the transparency goes to the beginning like AARRGGBB, so you color coulor also be
Alpha: 127
Red: 187
Green: 0
Blue: 255

How to apply opacity in Hex colors ?
I am working with CSS Hex colors. I am trying to apply opacity in Hex colors. I need #78909c with opacity 0.2.
The hex representation of colors supports the alpha channel to set opacity.
so, take any color in hex e.g. #ffffff and append 00 to ff (in hexadecimal representation) for opacity, i.e. #ffffff00 - #ffffffff
for your color: #78909c33
20% implies 33 in hex
Here is a demo
Reference: Hexadecimal notation
HEXA - #RRGGBBAA
There's a relatively new way of doing transparency, it's called HEXA (HEX + Alpha). It takes in 8 digits instead of 6. The last pair is Alpha. So the pattern of pairs is #RRGGBBAA. Having 4 digits also works: #RGBA
I am not sure about its browser support for now but, you can check the DRAFT Docs for more information.
§ 4.2. The RGB hexadecimal notations: #RRGGBB The syntax of a
is a token whose value consists of 3, 4, 6,
or 8 hexadecimal digits. In other words, a hex color is written as a
hash character, "#", followed by some number of digits 0-9 or letters
a-f (the case of the letters doesn’t matter - #00ff00 is identical to
#00FF00).
8 digits The first 6 digits are interpreted identically to the 6-digit
notation. The last pair of digits, interpreted as a hexadecimal
number, specifies the alpha channel of the color, where 00 represents
a fully transparent color and ff represent a fully opaque color.
Example 3 In other words, #0000ffcc represents the same color as
rgba(0, 0, 100%, 80%) (a slightly-transparent blue).
4 digits This is a shorter variant of the 8-digit notation, "expanded"
in the same way as the 3-digit notation is. The first digit,
interpreted as a hexadecimal number, specifies the red channel of the
color, where 0 represents the minimum value and f represents the
maximum. The next three digits represent the green, blue, and alpha
channels, respectively.
For the most part, Chrome and Firefox have started supporting this: enter image description here
From what I understand is that the minimum values for this CSS command is:
rgba(0, 0, 0, 0); /equivalent hex rgba #0000
and the maximum values
rgba(255, 255, 255, 1); /equivalent hex rgba #FFFF
Now, say we look at the r: its decimal is 255, and its hex is #F, which is easily expanded/converted to #FF.
#FF = 255
On the computer side, hex reads 0 to F (Base 16). On the human side, the decimal input reads 0.0 to 1.0 (Base 10). Essentially, there is only 10 acceptable inputs out of a possible 16.
So my question, what happens with the other 6 unobtainable input values? How does the alpha channel translate?
If you are looking for finer grained opacity settings you may use Alpha values with more than one decimal place. For example RGBA(255,255,255,0.05) will yield the expected results as a very light tint of White.
The answer was given here: Html rgba color opacity?
If you are using the rgba notation in CSS, remember that the last digit is used for opacity. So it's value it's not counted in the color rgb.
rgba(255, 255, 255, 1); The first 3 digits are for the rgb color value and the fourth digit 1 is for opacity and it could be also decimal like 0.5 for example.
Remember that IE8 does not support this notation.

Here is the screenshot of the map that I'm working on:
and here is my KML code:
<Style id="line1">
<LineStyle>
<color>ff8C0A23</color>
<width>2</width>
</LineStyle>
</Style>
<Placemark>
<styleUrl>#line1</styleUrl>
<LineString><coordinates> ...
As you can see the color value is ff8C0A23, it's ARGB, right? So the RGB color is 8C0A23 that should looks like this:
But as you can see the color of the border is shown totally different in the map. Anyone knows how to fix it?

According to:
https://developers.google.com/kml/documentation/kmlreference#color
The order of expression is aabbggrr
<color>
Color and opacity (alpha) values are expressed in hexadecimal notation. The range of values for any one color
is 0 to 255 (00 to ff). For alpha, 00 is fully transparent and ff is fully opaque. The order of expression is
aabbggrr, where aa=alpha (00 to ff); bb=blue (00 to ff); gg=green (00 to ff); rr=red (00 to ff). For example,
if you want to apply a blue color with 50 percent opacity to an overlay, you would specify the following:
<color>7fff0000</color>, where alpha=0x7f, blue=0xff, green=0x00, and red=0x00.

I am working with a piece of code that requires me to use 8 digit hex rgba values
-b [ --background-color ] arg (=efefefff) color of background in hex rgba
-f [ --foreground-color ] arg (=00000000) color of background in hex rgba
I cant for the life of me figure out what the 8 digit combination for black is
00000000
is completely transparent not black
can some help?
Black has no red, green or blue, but it is not transparent, so the alpha needs to be ff. Therefore the combination you seek is
000000ff
I want to write a function in ruby that given a number between 1 and 500 will output a 6 digit hex color code that gets linearly darker for higher numbers. This doesn't seem that hard but I'm not sure where to begin. How can I implement this?
edit
Hue seems like a more reliable way to go. I'd like to give a reference color, say a shade of green, and then darken or lighten it based on the input number.
input: 10
output: color code (in rgb or HSV) that is a light shade of the reference color
input: 400
output: color code (in rgb or HSV) that is a fairly dark shade of the reference color
edit 2
The only reason I need to use between 1 and 500 is because that's the input I have to work with. It's alright if some numbers that are close together map to the same color.
The 6 digit hex color code is in RGB.
What you want is to work in HSV: pick a Hue and Saturation, and gradually decrease the Value.
Convert from HSV to RGB to output the color.
See here for an example.
Basic linear interpolation?
// Pseudocode
function fade_colour(source, factor)
const max = 500
const min = 1
foreach component in source
output[component] = round(source[component] * (max - value) / (max - min))
endforeach
return output
endfunction
Why not just return a gray level then, #ffffff to #000000? 500 levels of darkness aren't really distinguishable anyway, and grays give you 256 levels.
If you only want to darken your reference color, it's easy. Given an R,G,B color that is the brightest you want to go, multiply each of the 3 values by (500-input) and divide by 499. Convert each of the values to 2 hex digits and append them with a # at the front.
