High And Low Pass Filter
A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).
A high point, level, or figure
greater than normal in degree or intensity or amount; "a high temperature"; "a high price"; "the high point of his career"; "high risks"; "has high hopes"; "the river is high"; "he has a high opinion of himself"
at a great altitude; "he climbed high on the ladder"
A high-frequency sound or musical note
a lofty level or position or degree; "summer temperatures reached an all-time high"
A notably happy or successful moment
less than normal in degree or intensity or amount; "low prices"; "the reservoir is low"
A low point, level or figure
A particularly bad or difficult moment
A state of depression or low spirits
an air mass of lower pressure; often brings precipitation; "a low moved in over night bringing sleet and snow"
in a low position; near the ground; "the branches hung low"

This purple color, or certain shade of magenta color doesn't act well with Digital Camera.
I think it is because of low pass filter on the Digital Camera, and way Camera Censor works.
To avoid those problem, you really should pick UV filter carefully as well as picking cloudy day with little UV as possible. So, color expressed on the censor or film will fall into more median range that everybody can see.
Also, violet color test Camera's dynamic range to the limit. As high frequency on the color spectrum is actually quiet challenge for both eye and censor.
Like shade or red/pink, Color I see is most likely different from you.
It is similar to lip stick argument between husband and wife(^^)
Sony ES CDP-X77ES with bottom exposed
Here is the stock underside of the TOTL CDP-X77ES cd player. Sony's flagship for 1990. Within the copper plated chassis, you can get a glimpse of the famous diecast transport (black square middle) with the KSS280A laser block, which was specific to this model. This transport also uses magnetic linear skate tracking (no gears) to move the laser along. High quality parts are used including Analog Devices opamps for low pass filter and non polar film caps for audio coupling and bypassing.
