Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_65068 ( "Project" text, "License" text, "Date" text, "Protocol" text, "Technology" text, "Server" text, "Client" text, "Web Client" text, "Multiple Sessions" text, "Encryption" text, "Authentication" text, "Data Compression" text, "Image Quality" text, "Color Quality" text, "File Transfer" text, "Clipboard Transfer" text, "Chat" text, "Relay" text, "HTTP Tunnel" text, "Proxy" text )

### Question ###
what is the color quality when the proxy is x, the encryption is x, the webclient is x and authentication is ?

### Accurate SQL ###

SELECT "Color Quality" FROM table_65068 WHERE "Proxy" = 'x' AND "Encryption" = 'x' AND "Web Client" = 'x' AND "Authentication" = '✓'
