- 239.255.255.250 FIRST this is multicast address,second SSDP uses this ip address Multicast (one2many) is a protocol to discover Universal Plug-and-Play devices on a network.For example, the IP address 192.168.123.0 is a wildcard with a netmask 255.255.255.0. Description239.255.255.250 is ok, is part of the System checking, must be allowed ever. Sum of RGB (Red+Green+Blue) 255+255+255765 (101 of max value 765).Red value is 255 (100 from 255 or 33.33 from 765) Green value is 255 (100 from 255 or 33.33 from 765) Blue value is 255 (100 from 255 or 33.33 from 765) Max value from RGB is 255 - color Use built-in color values, define custom colors, and use the alpha channel. FFFFFF (or 0xFFFFFF) is known color: White.HEX triplet: FF, FF and FF.RGB value is (255,255,255).

You can find a list of these colors at the end of this topic.Since white is (color 255 255 255), we end up getting 1/2 of 255 for the red and blue components and 255 for the green one. For example, Color.Red returns pure red. By using the Color enumeration, you can easily access the colors that are defined by HTML's Cascading Style Sheets (CSS). The prefix length determines the size of the subnet and is the number of 1 bits in the netmask.Number of Addresses Number of Bits Prefix Classful Notation Mask 1: 0 /32: 255.255.255.255: 2: 1 /31: 255.255.255.254: 4: 2 /30: 255.255.255.252: 8: 3 /29: 255.255. A optional Prefix Length can be specified in the form of an integer.

The alpha channel is represented by aa: 00 represents fully transparent, and ff represents fully opaque.The RGBA function returns a color based on red, green, and blue components. The string is in the format "# rrggbbaa" where rr, gg, and bb are identical to the 6-digit form. 8-digit hex value: As an example, "#ff7f5080" is the same as "Coral" with a 50% alpha channel. The string is in the format "# rrggbb" where rr is the red portion in two hexadecimal digits, gg is the green, and bb is the blue. 6-digit hex value: As an example "#ffd700" is the same as "Gold".

You can also use a percentage from -100% to 100%. -1 fully darkens a color to black, 0 doesn't affect the color, and 1 fully brightens a color to white. A number between -1 and 1. A color value such as Color.Red or the output from ColorValue or RGBA. You can also use a percentage, 0% to 100%.
