All hex-colors in three-digit or six-digit hex are pure colors, so #000000 will be black in all implementations that follow the official specification. Eight-digit hex means that the last 2 digits represent the alpha value.. so #ffffff00 works. It translates to 255,255,255,0 (white with an alpha of 0, which makes it transparent). This works with every color.. as long as it's eight-digit and the last 2 digits are 00, it will always be transparent. Answer from toi80QC on reddit.com

Here's a correct table of percentages to hex values for opacity. E.g. for 50% white you'd use #80FFFFFF. To think in terms of transparency instead, flip the order of the percentages (more opaque = less transparent).
| % | Hex |
|---|---|
| 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 |

Short answer: full table of percentages
You can see the full table of percentages to hex values and run the code in this playground in
- Golang https://play.golang.org/p/l1JaPYFzDkI .
- Kotlin https://pl.kotl.in/o9BnFYhRn
Ok the table tells the results not how to find the results. The next parts explain how you can calculate yourself.
Short explanation in pseudocode
Percentage to hex values
- decimal = percentage * 255 / 100 . ex : decimal = 50*255/100 = 127.5
- convert decimal to hexadecimal value . ex: 127.5 in decimal = 7*16ˆ1 + 15 = 7F in hexadecimal
Hex values to percentage
- convert the hexaxdecimal value to decimal. ex: D6 = 13*16ˆ1 + 6 = 214
- percentage = (value in decimal ) * 100 / 255. ex : 214 *100/255 = 84%
More infos for the conversion decimal <=> hexadecimal
Long answer: how to calculate in your head
The problem can be solved generically by a cross multiplication.
We have a percentage (ranging from 0 to 100 ) and another number (ranging from 0 to 255) then converted to hexadecimal.
- 100 <==> 255 (FF in hexadecimal)
- 0 <==> 0 (00 in hexadecimal)
For 1%
- 1 * 255 / 100 = 2,5
- 2,5 in hexa is 2 if you round it down.
For 2%
- 2 * 255 / 100 = 5
- 5 in hexa is 5 .
The table in the best answer gives the percentage by step of 5%.
How to calculate the numbers between in your head ? Due to the 2.5 increment, add 2 to the first and 3 to the next
- 95% — F2 // start
- 96% — F4 // add 2 to F2
- 97% — F7 // add 3 . Or F2 + 5 = F7
- 98% — F9 // add 2
- 99% — FC // add 3. 9 + 3 = 12 in hexa : C
- 100% — FF // add 2
I prefer to teach how to find the solution rather than showing an answer table you don't know where the results come from.
