-This is because the last two variants of //vals̈et// do not afford a greater semantic understanding - all three of these variants involve //valek//, //s̈elet//, and at least one absent spectral impression that would otherwise lie between them. These variants come with subjective impressions of a slightly shifted hue and lightness. We will revisit this phenomenon later.

 Instead, their word for saturation derives from **heavy** (//muri//) the more //heavy// a colour, the more it displaces the other spectral colours.
-The modifier word itself - //amur// - is a linguistic opposite of this concept, and we will translate it as //pale// (even if 'pale' describes both saturation and lightness effects in English and we are here talking //only// about saturation effects).

 The term //amur'inin// is rarely used explicitly, as it's the default modifier for a colour. In other words, //"valek"// usually means //"highly saturated red"//, unless there is reason to assume you are using the word very broadly, based on whatever context you're using it in.

 **amur valek** is roughly where the 3 in our example is - a definite red, but still rather subdued.
-**amur'ini valek** is roughly where the 2 in our exmaple is - the red is vivid, but not quite popping.
+**amur'ini valek** is roughly where the 2 in our example is - the red is vivid, but not quite popping.
 **(amur'inin) valek** is around where we have marked the gradient with 1 - bright, popping red, without any other spectral detractors.
-This affects compound colours much the same way - the less they are washed out by unrelated colour components, the more '//heavy//' and the less '//pale//' (//amur//).
+(**//amur'arar//** also functions as a colour by itself, if it isn't followed by any colour - grey - although it is then usually shortened to //amurra//.)

 Saturation modifiers also have some implications for //vals̈et//, the non-spectral colour we've been keeping our steady eyes on. Specifically, saturation is slightly reduced in the 'purple' and 'raspberry' colours due to the broader spectral influence on the colour impression (either //oso// or //idi// interfering with the 'pure' //vals̈et// colour). So we can adjust our table as follows:

+===== Scientific colours =====
+Spectral colour //ranges// also have **scientific names**. With the exception of //valek//, each primary colour of the kavkem qualia (//valek//, //oso//, //idi// and //s̈elet//) is covered by two of the ranges, though typically associated only with one:
+^ scientific term ^ wavelength ^ associated quale ^
+| banthu | ~500 to ~700 nm | valek |
+| tasath | ~400 to ~600 nm | oso   |
+| venthu | ~300 to ~500 nm | idi   |
+| edath  | ~200 to ~400 nm | s̈elet |
+The ~100 nm overlap implies that the colours must be shared between terms. And indeed, formally, //oso// is still in the //banthu// band, although near the edge, whereas it is closer to the center of the //tasath// band. Similarly, //idi// is still n the //tasath// band, but much more central in the //venthu// band. //s̈elet// manages to almost escape //venthu//'s grasp entirely, sitting almost exactly on its edge, and perfectly central to //edath//:
+{{:kavkem:colour-spectral-qualia.png?direct|}}
+The scientific terms are typically used when talking about the colour cones themselves, as theoretical absorption bands - they are not precisely defined by wavelength, but by the 'ideal' absorption in the retinas of creatures originating from Earth (or its scion Nekenalos).
+These terms are in use by (sufficiently literate) kavkema and local Threadwielders, but **not** by any other sapient species with knowledge of Kendane͡ivash, any more than the kavkem dialect colour names are relevant outside of Nekenalos.
