I've successfully changed it once by this.
then I want to change it to other colors, but my new code are not working, the color is still the old one.
I change like this(_theme.less
):
from@button-primary__background: @color-orange-red1;
to @button-primary__background: @color-dark-pink1;
I've Flush Magento Cache or Flush JavaScript/CSS Cache,
how can I make it change again untill the color I want?
