Describe the feature:
Include the transparency option on the color controls for "series color" on bars / lines / area (different from existing fill)

This feature exists on heatmap and table color by value

Describe a specific use case for the feature:
When I am including a series and its time shifted counterpart
I need to reduce the opacity of the shifted series using the same color
So I can visually see that it's a "shade" of the past

CC @elastic/datavis as this is most definitely a datavis design request / discussion

Transparency or better a different lighter opaque shade to avoid color differences between the dark and the light theme when rendering the chart.

[Lens] Color mapping for categorical dimensions (#162389)
b12a422 
## Summary

This PR introduces the new color mapping feature into Lens.

The color mapping feature is introduced as a standalone sharable
component available from `@kbn/coloring`. The
[README.md](https://github.com/elastic/kibana/blob/ddd216457d66912de43c7688ae99044c2c34bbd2/packages/kbn-coloring/src/shared_components/color_mapping/README.md)
file describes the components and the logic behind it.

The Color Mapping component is also connected to Lens and is available
in the following charts:
- XY (you can specify the mappings from a breakdown dimension
- Partition (you can specify the mappings from the main slice/group by
dimension)
- Tag cloud (you can specify the mappings from the tags dimension)

This MVP feature will be released under the Tech Preview flag.
This PR needs to prove the user experience and the ease of use. UI
styles, design improvements and embellishments will be released in
subsequent PRs.

The current MVP-provided palettes are just a placeholder. I'm
coordinating with @gvnmagni for a final set of palettes.

## Release note

This feature introduces the ability to change and map colors to break
down dimensions in Lens. The feature provides an improved way to specify
colors and their association with categories by giving the user a
predefined set of color choices
or customized one that drives the user toward a correct color selection.
It provides ways to pick new colors and generate gradients. 
This feature is in Tech Preview and is enabled by default on every new
visualization but can be turned off at will.
