Colors for the STEREO FLAGS and STEREO MARKS

[Vesdet]

As a Ketcher collaborator I'd like to implement rendering colors of the stereochemistry flags and labels.

In the ‘Settings’ user is able to specify the preferences for the rendering of the stereochemistry flags and labels.
Colors:
• Color of Absolute Centers - Specifies the color in which the stereo bonds, stereogroup labels, or both are displayed at absolute stereogenic centers.
• Color of AND Centers - Specifies the color in which the stereo bonds, stereogroup labels, or both are displayed at AND stereogenic centers.
• Color of OR Centers - Specifies the color in which the stereo bonds, stereogroup labels, or both are displayed at OR stereogenic centers.
• Color stereogenic centers - Specifies how color is used with one of the following values:
a) Labels only

b) Bonds only

c) Labels and Bonds

d) Off

Draw the default colors for stereocenters are:
Absolute – Red;
AND – MediumBlue
OR – ForestGreen
The color for the next label (AND1, AND2, AND3 or OR1, OR2, OR3…) is a little lighter then for previous one.

The possibility to specify the colors for stereogroup labels and stereo bonds at absolute/AND/OR stereogenic centers was implemented. Release/2.3 The issue is verified and closed.
