The daylights are definitely very blue, but most of the led grow lights I've seen these days are more pink than violet, if that would work for you.
If you're only worried about them surviving the winter, everything I saw in your picture should be fine without any extra light at all, as long as you water them and don't lock them in a closet 🤣 I've had lemon trees a few years now, and before I got the lights for them they would drop leaves in the winter, but still come back in the spring. With the light they keep their leaves all year round.
