Updating a preschool logo and need format Higher res

Hi our current logo is very dated and pixelated and so looks awful on letters, website etc we have had it re drawn as it is a child’s image and wanted it to stay roughly the same but is very similar design to the original a house with a child either side we would like it put into colour but not sure what colours it needs to look good on letters and website but also stitched onto navy blue work T-shirt’s originally was on red so may need two slightly different colour designs happy to have some input on this. I can send images of the old logo and then the new drawn one. We are a charity run preschool so only have a small budget
