This is academic to be honest. People who seen it as white and gold see clear white and clear gold.

I do not think they "see" white and gold.
It is the answer to the ill posed question, "What color has this dress?" Because it can mean:
- "What are the actual colors of the actual dress expressed in X,Y,Z"
This one needs the actual dress and a colorimeter
- "What are the actual colors of the actual dress expressed in color names"
This one needs the manufactures description of the dress, or the actual dress a defined lightning and then a bunch of people arguing about color names.
- "What are the raw R,G,B values of the colors in this particular file"
Thats an "easy" one. For a single pixel I exactly say what it is. It gets more complicated if we discuss an area.
- "What are the X,Y,Z values of this photo using the correct color space"
What is the correct color space? sRGB, most likely?
- "What are the X,Y,Z values of this photo after adjusting white point, black point, gamma adjustment, and in the correct color space.
Wait why do we have to do the adjustment, cannot we trust that the measuring device (a.k.a camera phone) did it correct? What is the correct black and white point, what gamma correction must be used. What is the transfer function of the sensor and what gamma correction was used for coding?
-"What are the colors by name you perceive using your display, background, actual surrounding lightning condition when you only look a individual patches but not the actual photo as whole"
Thats an interesting one and will give you different results then the next two ones.
-"What are the colors of the dress by name you perceive using your display, background, your actual surrounding lightning condition"
Thats a good one but look at the next one
-"What do you think what are the actual colors by name of the actual dress depicted in this photo"
Thats where surrounding, previous knowledge, and inherent assumptions comes into play.
Which one is asked, which one is actually answered?
Which one do you think is asked, which one thinks the one who gives an answer is being asked, which on to think was the answer given to?
PS: I most likely missed a few other interpretations.
