Transparent ARGB hex value

Question

The colors in this table is all not transparent  I guess the value for the A is set to FF   What is the code for transparency    For example this color FFF0F8FF  AliceBlue   to a transparent code such as   F0F8FF

User · Accepted Answer

Transparency is controlled by the alpha channel (AA in #AARRGGBB). Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent. Values in between are semi-transparent, i.e. the color is mixed with the background color.

To get a fully transparent color set the alpha to zero. RR, GG and BB are irrelevant in this case because no color will be visible. This means #00FFFFFF ("transparent White") is the same color as #00F0F8FF ("transparent AliceBlue"). To keep it simple one chooses black (#00000000) or white (#00FFFFFF) if the color does not matter.

In the table you linked to you'll find Transparent defined as #00FFFFFF.

If you have your hex value  and your just wondering what the value for the alpha would be  this snippet may help    x000D   x000D  const alphaToHex    alpha   gt    x000D    if  alpha  gt  1    alpha  lt  0    isNaN alpha     x000D      throw new Error  The argument must be a number between 0 and 1    x000D      x000D    return Math ceil 255   alpha  toString 16  toUpperCase    x000D     x000D   x000D  console log alphaToHex 0 45    x000D   x000D   x000D

Here is the table of   to hex values   Example  For 85  white  you would use  D9FFFFFF               Here 85     D9   amp  White    FFFFFF      100      FF 95      F2 90      E6  85      D9  80      CC 75      BF 70      B3 65      A6 60      99 55      8C 50      80 45      73 40      66 35      59 30      4D 25      40 20      33 15      26 10      1A 5      0D 0      00   How is it calculated   FF is number written in hex mode  That number represent 255 in decimal  For example  if you want 42  to calculate you need to find 42  of numbeer 255 and convert that number to hex  255   0 42    107 107 to hex is  6B     maleta
