That's why i can not reuse placeholder color in my component: http://rising-placeholder-input.surge.sh/

Thanks for filing the issue!

Tried checking the issue on reported chrome version 68.0.3440.106 using Ubuntu 14.04 with the below mentioned steps.
1. Launched Chrome
2. Navigated to http://rising-placeholder-input.surge.sh/
3. Tried clicking the input fields.
we observed everything seemed normal.
Note: Considering the URL in C#2 as test file.

@Reporter: As we are not very clear about "I get a black placeholder color with Javascript.", It would be highly helpful if elaborated on it. And please let us know if we missed anything in the test steps.

Once the input has a value, the computed placeholder color returned by Javascript is always black in Chromium

Tried checking the issue on reported chrome version 68.0.3440.106 and on version 60.0.3112.0 using Ubuntu 14.04 and mac 10.13.1
Our observations:
-----------------
When navigated to https://jsfiddle.net/4jbtouke/2/ and entered value in input field then text colour is seen in black. Similar behaviour is seen in 60.0.3112.0. Attaching the screencast from Mac, as we are facing technical issue while recording the screen on Linux.

@Reporter: Could you please have a look at the screen cast and let us know if the issue is seen in 60.0.3112.0(...from the screen cast) Any further inputs from your end may be helpful.

Thanks!

The screencast shows the issue in version 60.0.3112.0.

The getComputedStyle() method fails when pulling style info from ::placeholder CSS pseudo-element.
