Is it possible to request a particular colour scheme? Because we are not able to use the available colour schemes.

Yes, this is available for corporate account users only. 

The corporate account usually has 50 or more users using the Pro account (paid annually). 

If you don’t have the intention to give all your staff the Pro account to use, you can let them use the free basic account. You will need to purchase 50 or more Pro upgrade code and use it as and when you need them. Each code is valid for 2 years.

We can provide custom themes, colours, designs, functions and etc. 

Note: 

• all customisation will occur additional charges on top of the subscription fee. This depends on the contract you sign up with us.
• All customisation will only be valid for 2 years. You will need to renew a minimum of 50 Pro accounts or purchase 50 new Pro upgrade codes.
