One example of an application that only has the standard color picker is the pathetic Paint application included in Windows:
Find the HTML Hex Color Code
If you are looking at the standard Windows color picker dialog, you’ll see the Red, Green, Blue on the right-hand side, which is always in decimal.
The first thing you’ll want to do is open up Calculator, and then put it into Scientific mode using the View menu. We’ll use this to convert those decimal codes to Hexadecimal.
First we’ll enter in the first number (for Red) while making sure the radio button is set to Decimal:
Click on the radio button for Hex and you’ll get the first part of the hex code:
Note that if you get a single number or letter you should precede it with a 0. In this case the code would be 0D.
Now that we’ve got the first part of the code, we’ll flip the radio button back to decimal and add in the second value for Green:
We flip the radio button to Hex again and we have the second part of the code:
Now the code is 0D25, so let’s find the third part by entering in the blue decimal value:
And now we have the third part of the color after clicking Hex:
So now the full color code is #0D2599, which can be used when editing your html/CSS files… and you also learned how to convert decimal to hex. Here’s an example using the color:
BLUE!
Of course, this technique works anytime you know the decimal RGB codes for a color, not just from MS Paint.
