Yes, right now the colour picker on WPide doesn’t have that kind of control. It’s just an image of colours which you can then hover over with the mouse to pick out the colour your after.
When you select a colour it will be inserted into the input box and the right-hand side of that box will show you the colour but if you then modify the Hex value for the colour in the input box the indicator does not change to reference this, which indeed it should.
Also like you say, making the color darker/lighter should also be possible and I will try to implement that.
The idea with this colour picker is that the selection of colours will be changeable, it’s just one big image after all. So you will be able to click a little button there to choose a different colour swatch or image of your choice. So you could create your own palet of colours and upload that image or you could just upload your logo image and take colours from that etc. Sadly I couldn’t get this to work the other day as I spent too much time trying to get the image changing replacement implemented using a drag and drop interface!
So it’s in the pipeline, I will have an indicator visible for the colour in the input box at all times, will try and add the functionality to make that colour brighter/darker and I wil make it so that you can change the colour swatch/pallet image to one of your choosing and maybe give a few alternative defaults with more colour options.
Thanks for your feedback.
