Syllabic alphabets require large numbers of diacritics to represent all the vowels, I thought we could actually make a system similar to this alphabet chart
, but the diacrtics coming in two different colors. One application of this is the enhanced Tengwar, with two groups of tether that are in different colors from both each other and from the Tengwar, the specifics would vary according to the mode. One idea is for vowel strokes to be marked in one color, if placed over/under the following consonant, and in another if marked over the preceding consonant. So syllable inintial vowels would, in other words, be marked in a different color from the rest. The specics colors of the diacrtics would vary acconidng to the color of the text and the background. For black text on a white background, the colours would be red and blue, for white-on-black text, the latter would be green.
