Yes, you can configure the custom colouring for admin console by using myst

Prerequisites

• Create a plain text file in myst custom action

  • name:console-style

  • location:console-style.sh

  • content:

    #!/bin/bash
    
    FMW_HOME=$1
    if [ -z "" ]; then
        FMW_HOME=/u01/app/oracle/product/fmw1221
    fi
    BORDER_COLOUR=$2
    if [ -z "$BORDER_COLOUR" ]; then
        BORDER_COLOUR="red"
    fi
    
    echo "Backing up general.css and console.css"
    CSS=$FMW_HOME/wlserver/server/lib/consoleapp/webapp/framework/skins/wlsconsole/css
    cp $CSS/general.css{,.`date +%Y%m%d-%H%M%S`}
    cp $CSS/console.css{,.`date +%Y%m%d-%H%M%S`}
    
    echo "Adding Production styling to console.css"
    cat <<EOT >> $CSS/console.css
    #product-brand-name:before {
        background-color: $BORDER_COLOUR;
        content: "PRODUCTION";
        font-size: large;
        margin-right: 20px;
        padding: 35px;
    }
    EOT
    
    echo "Adding border colour"
    sed -i "/background-color: #FFFFFF;/a \ \ \ \ border: 8px solid $BORDER_COLOUR;" $CSS/general.css
    
    exit 0
    

• Create a Jython Action in the myst custom action

  • name: console-style

  • location: console-style.py

  • content:

    from com.rubiconred.myst.util import SSHUtil
    
    """
