TOP to POP
Summary
Position and Active is a shortcut for P in RGB, and alpha is set to 1 for active pixels (pixels with a valid attribute value).
Using Custom you specify which attribute and components you want in the RGBA of the TOP, so max 4 could be P(0) Color(2) N(1) P(2).
When you Use Dimension all pixels are active since the resolution matches the TOP When using the other modes you can end up with unused pixels (you have 40 points, fit to square gives you 7x7, so you end up with 9 unused pixels), alpha is only set to 1 for used pixels.

The color values as treated as being in the selected color space, and are converted to the Working Color Space before they are used as part of the node's operation. Note that this does not change the color space of the node itself, as that is always in the Working Color Space.

- Rec.2020
rec2020- Rec.2020 color space, with Rec.2020 (same as Rec.709) transfer function. Considered an HDR color space with respect to Reference White.
- DCI-P3

- ACEScg
acescg- ACEScg (also known as ACES AP1) color space, with a linear gamma transfer function. Considered an HDR color space with respect to Reference White.
- Passthrough
passthrough- When selected, the color values will be used as-is in the operation, without any modification or attempt to convert them into the Working Color Space.
Parameter Reference White
parmreferencewhite - ⊞ - When converting a parameter color value to the Working Color Space, this controls how it should be treated with respect to Reference White. If the Working Color Space is the same Reference White, then no adjustment is done. If they are different, then the Reference White level (brightness) of this color will be adjusted to the range expected by the Working Color Space. For example if the project is set to have a SDR Reference White of 120 nits, and the HDR Reference White is 80 nits, then a color of (1, 1, 1), which is 120 nits in the SDR color space, will be converted to be (1.5, 1.5, 1.5), which is 120 nits still in the HDR Working Color Space.
- Default For Color Space
default- Will use either the SDR or the HDR Reference White, based on the color space selected.
- Use Parent Panel
useparent- Will use the Reference White that the parent panel has selected. If the top-level panel also has 'Use Parent' selected, then 'UI Reference White' will be used.
- Standard (SDR)
sdr- Will treat the Parameter Color Space as SDR for it's reference white value.
- High (HDR)
hdr- Will treat the Parameter Color Space as HDR for it's reference white value.
- UI
ui- Will treat the Parameter Color Space as UI for it's reference white value. This uses the 'UI Reference White Nits' value for it's brightness.
