You can use different temperatures to 'mix' one in between, but your shadows will be different colors if that matters.
For a clip on light to work well it needs to extend fairly far out from the painting surface, otherwise the steepness of the angle can be problematic with reflections and shadows. Ideally you want the light at 35 degrees from the surface, from the top and behind you, or if that won't work, then from the side. Every small LED clip light I have seen had a very strange color cast to it, so be sure to either see it in real life first or buy from a source that allows you to return it easily if you don't like it.
I gave up on clip lights and went with a pedestal mounted light or a swing arm light with some good bulbs in them. The pedestal lights are easy to move to wherever you are in the house, but not good for away from home. You would need a clip on for that. The swing arm lights work great in a permanent spot on a desk or nightstand or even mounted to a wall. They are cheap enough you could have one in your most used locations.
