Color range selector

Yes I agree that it would be good, useful and interesting a custom specific component

Meanwhile of waiting for FF team to decide about this, you can also see the already available filters that are in the FF library about this topic that maybe you can use in some way

I do not know if it could be similar to what you may want and are suggesting, but may be something that is already available and can test it

Will tell what filter are related to this later

Thanks Rachel Duim and SpaceRay.

I know Color Range Picker with Median. It is a nice filter, but what I mean is someway different.
I try to explain.

First of all the component, when a color is selected, should select only that precise color, with all its characteristics.
Let's suppose that I pick the color AFFFAA:

This is the first important point.

The second point is how can we enlarge the action range?
We could have two solutions.

1) Let's consider AFFFAA as the center of a circular area with ray 0. Using a value 0 we would select only that precise color. Increasing the value to 1,2, ..... , the circular area would expand and we would have a wider color range.

2) A second option would be, as I already explained, selecting two colors. Let's consider two colors: AFFFAA and 1F5D1B.
The line connecting the two points would be the diagonal of a rectangle. That rectangle would be the area of our color range.
