1. Saturation
The saturation has a value between 0 and 1 and changes horizontally.
S =
1 - S =
Saturation remains constant vertically:
2. Saturation - When brightness is 1 (100%)
Step 1. Moving from a pure color (S: 1, B:1) to white (S: 0, B:1)
The distance between the RGB at saturation (S): 0 and saturation (S): 1 can be calculated as follows:
To predict the RGB code when the saturation (S) changes:
Step 2. MOVING FROM ALMOST WHITE (0 < S) TO PURE COLOR
Calculation of R', G', B' (S:1, B:1) by using eq.5:
Step 3. EQUATION COMBINATION
Plugging Eq.6 into the original equation (Eq.5)
3. Saturation: When brightness is ≤ 1
Displacement of saturation when brightness is equal or less than 100%.
Step 1 & 2. Determination of point C by using point A as a starting point:
Step 3. Determination of point D by using point C as a starting point
- Moving from C to D can be obtained by combining equations 3 and 8.
- The answers tells which equation is needed to predict D from A.
The expression:
(A) Is valid when the colors are within the same
hue range.
(B) Predicts the RGB code for horizontal
changes.
(C) B Initial = B Final
4. Saturation and brightness:
Horizontal and vertical changes
HOW TO PREDICT THE RGB FINAL REGARDLESS OF LOCATION
The expression:
(A) Is valid when the colors are within the same
hue range.
(B) Predicts the RGB code for horizontal and
vertical changes.
5. RGB prediction
CALCULATION OF RGB MAX, INTERMEDIATE AND MIN
The expression:
(A) Is valid when the colors are within the same hue range.
(B) Predicts the RGB code for horizontal and vertical changes.
