Depending on your application / need, you could use a color picker tool, or you could use your Browser's developer console, to be sure. But...

The default input placeholder color varies by browser.

In your screenshot, it's #8e8e8e

Some examples by browser:
In Chrome (Mac) it's #a9a9a9
in Firefox (Mac) it's #777777

Bootstrap 3 does define a "default" placeholder color, which you can see by inspecting the CSS a variety of ways - below is from the CSS directly (For Bootstrap v3.3.7):

.form-control::-moz-placeholder{
    color:#999;
    opacity:1
}

.form-control:-ms-input-placeholder{
    color:#999
}

.form-control::-webkit-input-placeholder{
    color:#999
}

So - Bootstrap 3 defines the default placeholder color as #999. (For reference, Bootstrap 4 defines the default placeholder color as #636c72).
