any camera $4k and up can be matched almost exactly the same to each other. proof below:

The flavor from red's ipp2 or arri's wide gamut comes from converting electronic locus points from light freq spikes that combine to produce hues and saturation into CIE colorspace. This is accomplished across the largest gamut possible without getting banding, noise, or glare from the special matrix combiner.

If you want to match things perfectly, you first either need at least 16bit RAW or first align the total overal gamma curve perfectly before hue and saturation. This is because with any other method, aligning the individual luma values per hue would cause banding.

Each camera has their strengths and weakness for dynamic range, noise color reproduction, etc. larger cameras have professional inputs, metadata, etc. that help post workflow automatically. red has 17 f-stops dynamic range and arri firmware clips color to 50ire.

More expensive cameras support greater precision with hue linearity where the hue maintains a straight light in the vectorscope across all exposures.

If you would like to read more about this, pm me. I have consolidated many, many articles of color science into a channel.
