O skakalnih lučeh

Explanation 1: “Light up”

 Generally speaking, the phenomenon of “lighting up” refers to the phenomenon of “homochromatic metamerism”:

Two color samples (one standard and one comparison sample) appear to be of equal color (no color difference or small color difference) under one light source (such as D65), while they exhibit significant color difference under another light source (such as A), which is called the “homochromatic metamerism” phenomenon

For this situation, we can describe it as’ lighting up '. That is to say, whether the sample can be matched with the standard sample for color matching depends on selecting a specific light source.

The fundamental reason is that the two samples have different reflections of light (reflection spectrum curves or visible band reflectivity), so it is called “Metamerism”.

The reasons for the “abnormal spectrum” include:

Sestava pigmentov, ki se uporabljajo za barvanje, je različna;

B、Različne metode obdelave itd.

Explanation 2: “Jumping lights”

 In fact, when we talk about “Tao light” in daily life, besides the above meaning, there is another layer of meaning:

 It refers to the situation where a single color sample undergoes dramatic color changes under different light sources. At this point, it can be described by “jumping the light”.

So, “jumping the light” can also be said to be a sample.

 Na primer, inženir za barvanje pri CIBA bi pri priporočanju barvila CIBA DEEP RED rekel: To barvilo pod svetlobo A ne postane rdeče.

(Avtor razume, da čeprav vir svetlobe A vsebuje veliko rdeče in rumene svetlobe, barvilo CIBA DEEP RED ne bo veliko bolj rdeče kot pod virom svetlobe D65.)
