Displaying all hexidecimal colors...

[Mhtml]

I have had a go at making a script to list all the hexcidecimal colors, I can easily get the non letter codes but getting ones with letters has me stumped.


<%
'MyArray = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", 1, 2, 3, 4, 5, 6, 7, 8, 9, 0)
for i = 00 to 99
response.write("<input onMouseover="&chr(34)&"ChangeColors(this.style.backgroundColor , this.style.backgroundColor)"&chr(34)&" class="&chr(34)&"this"&chr(34) & " style="&chr(34)&"background-color:0000"&i&""&chr(34)&">")
next
Response.Write("<br>")
for i = 00 to 99
response.write("<input onMouseover="&chr(34)&"ChangeColors(this.style.backgroundColor , this.style.backgroundColor)"&chr(34)&" class="&chr(34)&"this"&chr(34) & " style="&chr(34)&"background-color:00"&i&"00"&chr(34)&">")
next
Response.Write("<br>")
for i = 00 to 99
response.write("<input onMouseover="&chr(34)&" ChangeColors(this.style.backgroundColor , this.style.backgroundColor)"&chr(34)&" class="&chr(34)&"this"&chr(34) & " style="&chr(34)&"background-color:"&i&"0000"&chr(34)&">")
next
Response.Write("<br>")
%>
<style>
.this{border-style:none;height:13;width:5}
.that{border-style:none;}
</style>
<br><br>
<script>
function ChangeColors(CT , CBC){
cc.value = CT ;
ccc.style.backgroundColor = CBC ;
}
</script>
Hexidecimal code / color:
<input id="cc" class="that"><input id="ccc" class="that">


You can see at the top of my code I made an array, I know there has to be a way to cycle through each letter and number combination...

like it picks out the letter a and then writes aa ab ac ad ae etc until it has gone through each combination.

Also is there a way to stop the page loading until all of the fields have been placed on the page?

You should be aware that the "letters" only include "ABCDEF" and not the whole alphabet. You also don't need to include char(34) to get an inline double-quote, all you need to do is place two double quote marks in a row:

<% response.write ("<input type=""text"">")

Next you should know that the range of values is #000000 to #FFFFFF so you need six nested loops to run through the full range of possible values for each character in the code. Last is a simple note that 16 x 16 x 16 x 16 x 16 x16 is a very, very large number and your generated web page will be unmanagably huge. This project is simply not going to work.

Wow, I can't even count that high. ;)

If you're going to do it, I might suggest doing the so-called "web safe" palette (although modern browsers should support just about any hexadecimal color, I would think)... that should shorten the size a bit, at any rate, although I'm not exactly sure what the formula is for a valid "web safe" color. If you're interested you might want to do some "google" research. ;)

Just some intresting pages worth looking at:

For web safe color listing:

And...

Wow, my favorite site rears its head again! ;)

try this nice little script :)


<%
response.buffer=true
max = 10 'max is 255
for i=0 to max
for j=0 to max
for k=0 to max
hexval = hex(RGB(i, j, k))
hexcol = cstr(hexval)
if len(hexcol)<6 then
hexcol = hexcol & mid("00000",1,6-len(hexcol))
end if
response.write("<font color='#" & hexcol & "'><b>RGB(" & i & "," & j & "," & k & ") = #" & hexcol & "</b></font><br>" & VbCrLf)
response.flush
next
next
next
%>


Note that RGB values range from 0 to 255, therefore there are 256*256*256 = 16,777,215 different color permutations. So for the purpose of demonstration, I set max to just 10

okay

here's one (http://aspalliance.com/aspxtreme/aspnet/syntax/props/colortable.aspx) done in ASP.NET. :D

I haven't been able to connect to the net for a while so I tinkered around using RGB and HEx but could only get 3/4s of the colors.

In the end I realised I had to increase green by 1 each time red got to 255 and the once green was at 2 start blue counting up by 1 .....How to do it? I have no idea. lol :)

I have a better color picker now anyway, I got it from flashkit it is fairly small and loads as if it is a .gif it is that quick.

I don't even think I will use a color picker in the end..
