improved foreground text in widgets without focus

[gustavo-iniguez-goya]

For widgets' default state, use primaryColor with less opacity, instead of primaryTextColor.

Issue #85

[gustavo-iniguez-goya]

Original style (2.14):

dark:

light:

Proposed style:

For light theme style maybe is clearer the original style (2.14).

Another option could be to have another primary text color for dark themes (like secondaryDarkColor): primaryTextDarkColor or similar.

Hi, this looks fine to me. I see another problem (at least, it was one for me): The styles of several widgets are entered twice (wit different settings):

QDateEdit,
QDateTimeEdit,
QSpinBox,
QDoubleSpinBox,
QTextEdit,
QLineEdit,
QPushButton {
  color: {{primaryColor}};
  background-color: {{secondaryDarkColor}};
  border: 2px solid {{primaryColor}};
  border-radius: 4px;
  height: {{36|density(density_scale, border=2)}}px;
}

QDateEdit,
QDateTimeEdit,
QSpinBox,
QDoubleSpinBox,
QTreeView,
QListView,
QLineEdit,
QComboBox {
  color: {{primaryTextColor}};
  padding-left: {{16|density(density_scale)}}px;
  border-radius: 0px;
  border-radius: 0px;
  border-top-left-radius: 4px;
  border-top-right-radius: 4px;
  height: {{36|density(density_scale, border=2)}}px;
  background-color: {{secondaryColor|opacity(0.75)}};
  border: 2px solid {{secondaryTextColor|opacity(0.2)}};
  border-width: 0 0 2px 0;
}

@YeisonCardona This looks like a very important patch. Any possibility of merging? :)

Edit: @gustavo-iniguez-goya Actually... The dark theme looks better, but the light theme looks worse with this change. Too much color and too much fading! I noticed that the old, light theme used black for all unfocused fields, and colors for the focused field. That was great.

Perhaps the more correct fix is not to use "primary highlight color everywhere". But instead to ONLY affect the dark mode, and to use a light-gray color for the unfocused fields in dark mode. Similar to how light mode works.

Hmm wait a minute @gustavo-iniguez-goya ... Any idea why your original text looked like that (dark text on dark theme)? Is it a Qt library change maybe? Because the official screenshot for this theme shows that dark mode is working for the theme author, there's no color problem there:

Maybe it's a matter of PySide vs PyQt, or newer GUI library versions breaking the theme, or an OS/platform issue.
