...I really do not know why you seem to look for fault in anything I seem to 
try to help others with...do not contradict or impune my profession/experience. 
The many, many years I have devoted to the practice and teaching of 
architecture, art, design, graphics and basics of photography not to mention 
enginnering, design and specifications on many types of construction and 
building types. 

The operative word is "TRANSLUCENT", yes there are "OPAQUE" pigments used in 
any kind of paint you can imagine, and sometimes used purposely to 
cover/block/change the appearence of a surface. If one purposly wanted to us 
"OPAQUE" paint to block out light through a window/skylight or "TRANSPARENT" 
surface, this is fine!

However, in "most" cases the reason a skylight/window/transparent surface is 
used, is precisely to ALLOW light to enter, sometimes with no interference = 
"TRANSPARENT", sometimes with a "filtering", "diffusion", "coloring" = 
TRANSLUCENT"

The word "OPAQUE" basically refers to a condition that is not able to be 
penetrated (in this case-light cannot penetrate).
The word "TRANSLUCENT" refers to a condition that allows penetration (of light) 
with a"filter" or "medium" (in this case transparent white paint)..trans = 
through; lucent = light!
            (an example would be parts of a stained glass windows)
The word "TRANSPARENT" refers to a condition of full penetration (of light) 
with, nothing blocking (in case of glass - seeing through); trans = through, 
parent = clear!

NOT exact translations of Latin/Greek etc., more directed towards teaching 
university, architecture, art and photography students about, characteristics 
of light, color and characteristics of materials, surfaces and interaction with 
light, penetrating through and reflecting off of surfaces.

Please note that I used the word "TRANSLUCENT"....meaning in this specific case 
of skylights in a building, allowing light through!

For clarification, and for those that did not catch the post that led to the 
below comments, the previous post, was answering a list members question about 
skylights in a building and should it have white paint or clear glass
