Hi Taylan ,
We have created a vue sample using scss for tailwind theme, as you
mentioned we have customized the primary color by overriding the existing
$primary variable. On modifying this variable the changes will
reflected for all the components which uses $primary as a variable name.
Also , if you want customize the entire control you can achieve this by
changing the variables maintained as $primary-text-color, $success,
$content-text-color-alt1. So, you can find reference of variable in the below
UG documentation. For tailwind theme the definition file is maintained in
folder path as mentioned here
(../node_modules/@syncfusion/ej2-base/styles/definition/_tailwind.scss) .In
this definition file if you override the primary color variable in the
application level it will be reflected in the areas were $primary color is
utilized ,based on this we have modified a vue sample in this primary color
variable has been overridden due to this primary color used in the sample is
been changed for the components you can refer the below sample,

Please refer the below UG documentation,
