When I use the color picker dropper tool to pick a color form the page, the format ends up as HEX and when transparency is lowered it’s an 8 digit hex with alpha transparency (example: #d8c4b17a) instead of the usual RGBA format. I much prefer RGBA because you can see the transparency value represented in a number (0.5 = 50%… 1 = 100%, etc). Is there a way to make it always use RGBA? I don’t want to have to go and open an online converter every time I use the dropper tool.
Hey @threeoten,
Thanks for posting in!
The color field in the picker accepts a variety of colors. It can accept HEX, HSL, RGB, or even just a color name.
If you always want RGB or RGBA, follow these steps.
1.) Clear out the field value
2.) Click the “Reset” icon and the color will be set to “Transparent”
3.) Select any color in the color picker and it will populate color field with RGB
Hope this helps.
Yeah I understand all that, but my post was specific to what happens after you use the dropper tool within the color picker. Go ahead and try it, use the dropper tool, click somewhere on the screen with the dropper tool and you will see the color that is registered by your click will be HEX and not RGBA.
The default in cornerstone always seems to use rgba, EXCEPT when using the dropper tool… then it’s hex. Why is that?
