On the Subject of Color Braille
This doesn’t feel right, but at least it looks good.
This module will show 30 colored dots. Each dot is in a color that is composed of a red, green, and blue component according to additive color mixing (see Appendix 1). Decompose the colors into their red, green and blue channels to obtain three words written in Unified English Braille (see Appendix 2).
However, one of the three words has been mangled in one of the following ways:
- Each of the three rows of dots may have been shifted one dot to the left or right.
- Each Braille letter may be upside-down (rotated 180°).
- Each Braille letter may be horizontally flipped (mirrored).
- Each Braille letter may be vertically flipped.
- Each Braille dot may be inverted (dots are non-dots and non-dots are dots).
Identify which of the color channels contains the mangled word and the specific mangling applied. Then touch the dot in the position given by the following table (dots are numbered in reading order):
|Mangled color channel →||Red||Green||Blue|
|↓ Mangling applied|
|Top row shifted to the right||1||9||16|
|Top row shifted to the left||17||5||3|
|Middle row shifted to the right||4||28||13|
|Middle row shifted to the left||2||6||21|
|Bottom row shifted to the right||20||25||15|
|Bottom row shifted to the left||22||23||30|
|Each letter upside-down||11||18||8|
|Each letter horizontally flipped||10||24||29|
|Each letter vertically flipped||26||14||19|
|Dots are inverted||27||7||12|
